Thanks for reporting this.

...as written according to
http://validator.w3.org/feed/check.cgi?url=http%3A%2F%2Fexport.arxiv.org%2Frss%2Fquant-ph
it is a vaild feed.

Confirming.

This is what I have been able to find out about this bug:
- The error message I'm seeing is 'rss_ni_adding_failed', in callbacks.c, line
1134.
- This message is displayed, because errors in refreshing is set in ui_feed.c
line 1008, which means there is no data in request->data.
- when download_info_cb in net/download.c is called after attempting to
download the data, the result in finfo_res->result != GNOME_VFS_OK, so you end
up in the else part around line 230 ('error during information request')
- This led me to suspect gnomevfs. And indeed:

Error: File not found

I'll file an upstream bug report with gnomevfs.
