Hello,

I get a segfault on my system with akonadi_imap_resource. I do not remember 
that I did anything particular change in akonadi, kmail, or my IMAP server, 
recently. I have not yet tried to setup a new imap account.

I would be happy to provide debug information on this issue, if it helps to 
make akonadi more robust, otherwise I just try to setup a new imap account.

I developer information I get in the KDE Crash Handler (do I need to install 
additional -dbg packages or run with KDE_DEBUG?):

Application: bokomoko of type IMAP E-Mail Server (akonadi_imap_resource), 
signal: Segmentation fault
Using host libthread_db library "/lib/i386-linux-
gnu/i686/cmov/libthread_db.so.1".

Reproducible: Always

Steps to Reproduce:
Happens right after login, no further action needed.




The problem depends on the user configuration, i.e. I see it right now only for one user, for another user I do not see the crash. Even if both users use the same server (not same mail account on the server).
