-- Information about the crash:
- What I was doing when the application crashed:
When opening Kontact and just viewing Messages (without clicking anything) Kontact crashes after a view seconds. Output on the console:

*** KMail got signal 11 (Exiting)
--

- Unusual behavior I noticed:
At startup, KDE gives two warnings/errors (I cite the original German text to be accurate)
.) "KMail-Ordner: Abbruch durch Benutzer (Der angegebene Ordnername ist leer)" -- KMail cancelled by user (the given folder is empty)
.) "Die Ressource 'KMail-Ordner' ist nicht funktionsunfähig. Die Ressource ist nun 'Online'" -- The ressource 'KMail-Folder' is not not-working. The Ressource is now 'online'. (Very strange message)

The crash can be reproduced every time.
