Random email application (modest) crashes with CSSU

20.2010.36-2 CSSU 36-2maemo11
EXACT STEPS LEADING TO PROBLEM:
1. Have GMail and MfE accounts configured
2. Use them normally, e.g. try to open a new email message
email works more or less as reliably as in officially supported firmware
Modest definitely crashes more often than it did with the official 36-2.
less than 1/10
EXTRA SOFTWARE INSTALLED:
Core dump of the crash would be welcome (or gdb output). See
http://wiki.maemo.org/Extras-testing#Tools_for_testers for more info, but note
that coredumps can contain private data.
Possible dupe of bug 11861?
Crashes appear to be caused by speed of scrolling. Fast scrolling of emails
tend to crash modest. Scrolling slowly doesn't.
Speculation: some routine in modest can't cope with the amount of data
generated when scrolling fast. Data generated by the scrolling can't be
processed and possibly do a buffer overrun or similar issue.
(Sorry not to provide any log, but I do not have the tools installed)
For me it crashes most frequently while checking for new emails, say, 4/10. I
have two IMAP accounts configured, neither of them are GMail or MfE.
*** This bug has been confirmed by popular vote. ***
Mine always does it when I skype call and try to check emails.8/10 will
instantly crash when I open the email client.It happens less frequently when I
play videos (tvcatchup stream while checking emails) maybe 3/10 and 1/10 when I
try to browse and check emails at the same time.It looks like it crashes when I
multitask.It doesn`t happen (so far) when I just check emails without anything
intensive happening.Bear in mind that my phone is overclocked @1000 AND was
solid stable for the past year at that speed with nothing crashing but since
the SSU update the email client is affected.
For me, Modest crashes constantly even when I am not using it..
I have disabled it from starting up automatically but if I try to open Modest I
get an instant crash.
Whenever I connect to the internet (both wifi and 3g) modest tries to open in
the background but crashes instantly resulting in an error notification. Never
had this problem with CSSU until the most recent update.
I have tried installing an older version of Modest but I still get this error
so it isn't a problem with Modest itself but maybe the CSSU update changed
permissions to an area Modest loads from??
With the latest update the story on my phone is different.I have no longer any
email crashes!I even overclocked my phone to 1500Mhz (up from 1000) to prove my
point.No more crashes!It looks like its not the CSSU update fault but a third
party application that makes your phone behave like that.I would suggest a
clean format and install of CSSU without any other software involved.Only then
you will be sure that it`s not CSSUs fault.

Default modest (3.4.8+0m5) doesn't cause me these caches. I have 7 email
accounts and I'm wondering if maybe this has something to do with it. Usually
people have 2-3 accounts. Crashes happens when I'm updating accounts or

i find it hard to believe that a 3rd party app would cause modest to crash. I
got the latest cssu update (...maemo14) and for me it still crashes, most often
while scrolling a message.
What is the status of this?
The crashes are getting really frequent which makes email almost unusable. Who
is maintaining modest in CSSU? If a newer version of modest is included in
CSSU, I think there should be an accountable maintainer for it.
Despite new update (14.1) I still experience random crashes, but because
everything else works very well, I'm not prepared to reflash my N900. I hope
that these crashes won't become more frequent.
I confirm frequent crashes with 3.90.7-8.

Guys! This is what is happening.I thought a third party app would crash the
email client, or an overclock or something else, but it`s not.I`ve tried
opening up the client and then before it loads everything do a fast scroll on
one of my email accounts.....result....crash! So I confirm this even with the
newest update.But when I leave it load up everything and do a fast scroll it
Could someone post a link with howto:
1. Enable core dumps on Maemo
2. Get debug info for the modest binary
3. Get gdb on the device or get the core dump analysed on the PC
These crashes happen a few times a day so with a few core dumps it should be
possible to get some info...
When my phone rebooted after the last cssu update automaticly, the message
"operationg system updated" AND -at the same time- "application 'email' closed"
appeared without even touching the phone. that means that without user
interaction the bug occurs.

Hi Andrew. I have some questions regarding a core-dump. Shoul I use
sp-rich-core? Or is there anything else. And does the process need to be
started or is it done automatically? Because the crashes are quite random. I
had to start modest from x-term quite a few times to try and see the output of
the error. Frankly I was quite disappointed from the small output. Hopefully a
core-dump may help you better but I am a bit unsure on how to do that.
These are four core-dumps that I got of modest. I couldn't attach them here due
to file size: http://www.mediafire.com/?7zdiznlva4z973k
Modest Version: 3.90.7-8
E-Mail Accounts: GMail, Hotmail, MFE, Nokia Messaging (all done using Wizard) +
POP3 account entered manually.
Core-Dumps were generated during random events like Send/Receive, Read E-Mail.
The four crashes all occurred within 2 minutes.
I wonder is anyone taking care of these problems? I posted 4 core-dumps 5 days
ago and received no feedback. I don't even know if they would be useful.
Anyway I have more core-dumps to post if they can help anyone. Here's a link:
I don't know how to analyse them myself(if anyone can share please do). For me
they are just gibberish.
The e-mail client is frankly a pain to use with all these crashes. I have
decided to install the normal version of the e-mail client. For any of you in
this mailing list who experience these random crashes and wish to do so too
here's how (without quotes obviously): "apt-get install modest=3.4.8+0m5"
I hope the crashes stop now.
If anyone wishes to submit core-dumps but doesn't know how it is quite easy
1. Add the following repository to your N900 using the default application
manager (Open App. Manager > Drop-Down-Menu > Application Catalogs > New).
Name: fremantle tools
Components: free non-free
Then press Save.
2. Close the application manager and open X-Terminal. In xterm enter the
following commands as root (you need the rootsh package).
apt-get install sp-rich-core
This will save core-dumps to your memory card in a folder called core-dumps.
Hope this helps.

I understand. I just wanted an acknowledgement. Like the one you just posted.
That someone will look into this eventually. I was in no way expecting someone
to look into it now.
I analized every single core dump posted by Robert and all of them are Out Of
Most of the crashes are reserving a new GSlice of memory using GLIB GSlice
functions like g_slice_alloc(), g_slice_new(). There are also crashes in
g_strdup and derivates (g_strdup_vprintf) and the like.
All of the crashes are in Camel functions inside Tinymail.
My Modest has never ever crashed so I wonder what could be different.
Mailboxes with thousand of folders?
My Modest is configured with two IMAP accounts, three Nokia Messaging accounts
and one POP3 account (Hotmail) for a total of 6 accounts and I can't get a
crash. I have viewed 13,000 of emails clicking next several times and going in
and outside folders hundreds of times with no results. I have left it open for
several days, polling all my accounts every 10 minutes, and not even a single
crash so far.
Now, even though I see there could be a memory leak in
tny_camel_store_account_get_folders_default() by not freeing the
camel_store_get_folder_info() call results, I still wonder why Modest 3.4 works
for you with absolutely no crashes since they both use the same version of
Now if you tell me that stock Modest 3.4 crashes but not that often as 3.90
CSSU then maybe we have a lead.
So if anyone want to give a try install the .deb attached, reboot your device
and test for more crashes. New dumps will help.

Hi thanks for your response. When I downgraded I broke the CSSU installation
but everything still worked quite well. But there still were crashes. I was
quite disappointed. I am pretty sure I never had crashes (or very rarely)
This also happened before CSSU. When I upgraded to v3.9 released by MAG, these
crashes started. When I downgraded again, the crashes stopped (or became rare).
After installing CSSU, the crashes started again but downgrading didn't help,
or didn't help much. I had broken the CSSU installation and the crashes were
still there with v3.4 So now I fixed everything and am working with v3.9.
I may have some core-dumps of crashes I had with v3.4 if you want.
Thanks a lot.
Modest became unuseable for me, post-CSSU upgrade.
I have 2 Gmail accounts configured, 30 min refresh interval over Wifi. I purged
almost everything from my Inboxes, hid all but 8 or so of my Gmail folders
using the Gmail IMAP tweaker, and deleted my local IMAP caches. At 12 pm, the
background refresh crashed (I got the usual crash notification). I wonder if
it's related to CPU/load? That could explain why it crashes on scrolling for
I presume the new auto-rotation is monitoring D-Bus for notification of
rotation. Since that's the principal area of the code that was changed, perhaps
something is timing out? of
In the space of 10 minutes, I opened my mailbox 6 or so times and Modest
crashed each time when I clicked a message to view. sometimes while Inbox was
Robert, thanks for your message. I have downgraded like you, and can open
messages again. I am trying the patched libtinymail also.
I respect the devs are volunteers, but I feel this bug may not be getting the
attention it deserves.
Hi naikel. I tried the patch you attached but I feel the problem got even
worse. It may be my impression but I think it is crashing more frequently. I
reverted to the previous version I had now. If you want I can post some more
core-dumps. Thank you very much for looking into this.
Hi Ashley. I am glad v3.4 is working fine for you. I had no such luck
Please forget about the tinymail patch I posted earlier. It really seems it
worsened the situation for several people.
I still see that all the crashes happen in functions that handle memory. I
could catch some crashes in my own N900. All of them under
camel_store_get_folder_info() and usually in a g_free() or something, so I'm
gonna try another approach and use something like dmalloc to see if all memory
is addressed and freed correctly.
Another thing I want to comment: CSSU uses Modest 3.90.7. After that version
we started bug fixing and few enhancements. The stock PR1.3 Modest is 3.4.8.
As you can see there's a long way from 3.4.8 to 3.90.7 where CSSU wasn't
involved, and I strong believe these crashes are not the cause of CSSU
modifications to Modest (most of them just to make Modest look good in
I'm pretty sure that if you compile the original Modest 3.90.7 (not CSSU) from
gitorious you'd still get the crashes. CSSU didn't introduce them.
CSSU team will of course do anything possible to fix bugs that we believe were
introduced by the original Modest coders by mistake. And, we thank them
(Modest coders) because of them at least we have a decent email client.
I was thinking, perhaps we could drop back a few minor versions in the upstream
code and see where the crashing begins?
I'd be happy to test Modest packages based on upstream and report back.

Well not sure if this helps, but I did a reflash of my n900 and install cssu on
top of it. So far there are no crashes with modest, it is up and running
without any issues.
Was there a new patch applied or something? I checked the version installed and
it still seems to be the one which was crashing.

Well you are lucky. I don't think there were any changes either. However mine
still crashes constantly. When I have some time I will reflash the phone (it
takes time to re-install everything), but I sure will stay away from v3.9 of
1st time it happened I updated to that version. Installing CSSU didn't help (as
expected). Then I reflashed and everything was fine again..until I made the
mistake of installing the CSSU with this version of modest included.
I really don't know what's causing this. I must have accumulated close to 1GB
of core-dumps..but I don't understand them and don't know how to fix it.
i have cssu installed and suffer these random scrashes and also 11993 Mangling
email addresses 
getting modest=3.4.8+0m5 did help with 11993 Mangling email addresses , but
the random crashes remain, so it seems that they are not related to the modest
version as such.
This seems to happen specifically with me when new mail is coming in, and I'm
trying to do anything else with modest, including after a complete
wipe/reinstall. If I try to read an email and others are coming in (MfE and
Nokia Messaging are configured, the latter with 5 IMAP accounts attached),
which can be incredibly frustrating.
Running CSSU 20.2010.36-2maemo15.

Sorry, that last email sentence should have read "If I try to read an email and
others are coming in (MfE and Nokia Messaging are configured, the latter with 5
IMAP accounts attached), the client crashes, losing whatever I happen to have
been doing - reading or composing - which can be incredibly frustrating.
The new CSSU update didn't fix this issue. Thank god for backupmenu. I tried
updating via HAM and via terminal. Well looking at the updated components there
seem to be little or no change to modest so this was expected. For the past
months, I have been running without CSSU and modest worked perfectly.
Since this problem doesn't seem that it will be fixed anytime soon, is there a
way for me to pin all the required packages associated with modest so that they
don't get upgraded? I wish I could upgrade to CSSU but modest crashes always
start all over again. Or else is there a way to upgrade to CSSU packages
manually and omitting the modest ones?

actually i have noticed now over time, that with "apt-get install
modest=3.4.8+0m5" modest almost doesn't crash and if it does, it happens very,
very rarely, but i have tested the latest modest from CSSU for two days now and
it does crash all the time, much more that the 3.4.8 does.
This got fixed with the latest update, the modest binary was thumb compiled
and that lead to all kinds of segfaults.
