Well, I added an event as uncounted times before, but Kontact crashed this times. I'm using ressources on a Kolab 2 server via DIMAP, some shared folders are installed as well. However I don't think that this might be the cause of the crash.

Using host libthread_db library "/lib/tls/libthread_db.so.1".
