Application: akonadi_imap_resource (4.9)
KDE Platform Version: 4.9.2
Qt Version: 4.8.2
Operating System: Linux 3.2.0-33-generic-pae i686
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
0. I run two kde user sessions in parallel.
1. Switched to current session from the other kde user session (using Switch User button on panel)
2. Got a certificate error from KDE (see below).  Might be a time-out issue??
3. Asked it to remember the certificate forever
4. IMAP crashed straight afterwards, causing bug report


- Unusual behavior I noticed:

I seem to have frequent problems with server certificates when switching between user sessions.
It comes up with the same error dialog ("accept certificate forever", etc). I select Forever, but its certainly not forever as it keeps reoccuring in the exactly same way.
This same problem keeps happening every so often (ranging from once a day or more, up to a few times a week on a good week).

- Other:
Seems to related to bug report # 302,459 (IMAP dialog timeouts) but not exactly the same.  So both might have a similar root cause?

The crash can be reproduced some of the time.
