Sentry Crash Report:

Description Christian Reiner 2012-07-06 05:04:08 UTC 
Application: akonadi_imap_resource (4.8)
KDE Platform Version: 4.8.4 (4.8.4) "release 7"
Qt Version: 4.8.2
Operating System: Linux 3.4.3-30-desktop x86_64
Distribution: "openSUSE 12.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
The system had a longer period of high network load that lead to several timeouts of different applications. The system runs fine otherwise. 
I restartet the akoadi server and retried, it appears the crashes can be reproduced. I will try to restart the whole system in a minute.

The crash can be reproduced every time.

-- Backtrace:
Application: c-r.info of type IMAP E-Mail Server (akonadi_imap_resource), signal: Segmentation fault

Comment 1 Christian Reiner 2012-07-06 05:24:06 UTC 
I tried these steps, none of it fixed the problem: 
- restart agent
- restart akonadi server
- restart the system
- remove and readd the imap ressource
The resource always crashes after a few minutes. Nevertheless it does report and fetch old and new messages. The resource is therefore unusable: this is a BLOCKER.
Comment 2 Christian Reiner 2012-07-06 05:41:13 UTC 
Surprising enough I got that issue fixed by restarting the imap server !
It is a cyrus imap server in version 2.3.16. Since that restart I did not experience a single crash anyone.
Comment 3 Christian Reiner 2012-07-06 09:01:17 UTC 
Unfortunately I have to report that the issue is _not_ fixed. 
It appears the ressource still crashes, but not in all situations. I will keep an eye on that (cannot really miss it, error popups every few minutes). I got the impression these crashes happen when there are latencies in the network connection.

Comment 5 Christian Reiner 2012-07-14 00:46:15 UTC 
Additional information: 
I fixed a problem on the imap server (cyrus-2.3.16), an invalid 'Trash' folder 
Wherever that came from (akonadi?) this fixed most of the problems for me. I do not experience any more crashes, though the imap resource is pretty slow (unresponsive) right now. 
This fits to what I saw in the mail client: diggin deeper I saw a message about a "non existing job" being queued.
