feedlist.opml - news reader crashes when refreshing this list

Comment 2 Neil MacLeod (reporter) 2007-08-07 05:13:55 UTC

I'll not fix this problem by deleting/replacing files (as I have a backup of
feedlist.opml from last week which did work) for the next two to three days in
case anyone from Maemo/Nokia wants me to submit more files or check anything.

The problem will probably disappear after a reboot. Try narrowing it down to a
specific feed.

Hi Jason, thanks for the reply. Rebooting made no difference - the feed reader
still crashes as before.

Before I meddle with the available feeds and possibly "fix" the problem (thus
eliminating my reproducible situation which may yield further details if anyone
from Nokia/Maemo responds) can you test with my feedlist.opml and see if you
can reproduce the problem on your device? If so I'll be able to narrow down the
feed safe in the knowledge I can get back to the broken state by restoring my
feed.

Comment 5 Neil MacLeod (reporter) 2007-08-07 18:59:54 UTC

Changing status - I would appreciate any assistance from Nokia before I "fix"
this issue and am unable to investigate further.

Comment 6 Neil MacLeod (reporter) 2007-08-07 19:00:22 UTC

Status == Severity. Bah.

I'll give it a shot a little bit later tonight.

Compressed tar containing /home/user/.osso_rss_feed_reader directory and
contents (cache, opml etc.)

Just in case the cache is playing a part in this issue and using my
feedlist.opml file is not enough to reproduce the problem, I've attached a
compressed tar containing the entire /home/user/.osso_rss_feed_reader
directory.

If anyone wishes to confirm if this issue is reproducible rename your existing
directory and untar this file (may require a reboot?) then refresh all feeds in
the main RSS application.

Thanks Jason. :)

Comment 10 Neil MacLeod (reporter) 2007-08-09 06:15:05 UTC

After further investigation it appears that it's "The Register" feed/cache
which is causing the Feed Reader to crash - if I refresh this feed alone, it
will crash the main Feed Reader application, and the remaining 9 feeds will
refresh individually without any problems.

I'm unable to determine _why_ "The Register" feed causes the application to
crash, perhaps it's a corrupted cache file (in cache/feeds/rivqwfo). However if
a Nokia/Maemo/community developer were to restore the
/home/user/.osso_rss_feed_reader directory (attached in comment #8) it would be
possible to reproduce this issue and debug it to a conclusion.

Try validating the feed. Perhaps there's something on their end that needs
fixing.

According to the feedlist.opml I've attached to this bug, "The Register" feed
is http://www.theregister.com/headlines.atom and it's valid. Even if the feed
wasn't valid, the application should not crash.

To fix the problem I had to unregister and then re-register the feed, which has
resulted in new cache entries being created so I'm not sure it's the feed or
feedlist.opml content but rather a corrupted cache, which needs investigation
by someone able to debug the application. At least this is easily reproducible
given the attachments to this bug so hopefully it will be fixed.

Comment 13 Neil MacLeod (reporter) 2007-08-12 23:59:35 UTC

This bug has re-occured - I fixed it by unregistering then re-registering "The
Register" feed, but after a day or two the RSS Feed Reader has started to crash
again whenever it attempts to refresh "The Register" feed.

*ANY* feedback from Nokia would be much appreciated.

Comment 14 Eero Tamminen 2007-08-13 17:01:04 UTC

Noticed this was reproduced also with development version of RSS feed
reader in NB#65565:
> 1. opened browser and typed in: www.theregister.com/headlines.atom
> 2. pressed orange RSS icon to get it into RSS application
> 3. Add feed dialog appeared - pressed OK
> The result was immediate exit/abort of RSS reader.

Comment 15 Neil MacLeod (reporter) 2007-08-14 05:05:57 UTC

Eero, thanks for confirming you have reproduced the probelm - I assume it will
be fixed in the dev version? Any clues what may be causing the problem in the
production version (in case any other feeds produce a similar effect and can be
corrected)?

In comment #13 I said I had added the feed back without any problems, but now
I'm not able to do this (the RSS app dies straight away). Strange, maybe I was
confused. :)

Not yet.

Maybe the feed changes?  Or there are some extra conditions?

Any change if anyone actually saved the atom file that generates the cache
entries ? Bug is most likely there and it would help alot in reproducing this.

Archive of the cache is already attached this bug... :)

Comment 19 Neil MacLeod (reporter) 2007-08-16 18:28:51 UTC

Woops that's not what you asked... I'll see if the atom feed is still a problem
today and attach it later.

Several problems have been found:

Comment 22 Andre Klapper 2008-06-04 11:56:45 UTC

According to the internal ticket, this specific issue has been fixed and
verified for osso-rss-feed-reader version 1.4.34 and later.

Closing as FIXED, please reopen if you can still reproduce this with the
mentioned version.
