Application: kmail (4.7.3)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-12-generic x86_64
Distribution: Linux Mint 12 KDE

-- Information about the crash:
It happens everytime i try to start kmail, it shows the UI and crashes immediately.

When I try it about ten times, it happens that there is a stable kamil running, but not reproducable.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
