Bug 310025

Application: kmail (4.9.3)
KDE Platform Version: 4.9.3
Qt Version: 4.8.3
Operating System: Linux 3.6.6-1.fc17.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
- What I was doing when the application crashed:

I stared Kmail.

Suspect this is triggered by Akonadi issues, as MySQL dies underneath Akonadi regularly. But then Kmail should then simply tell the user that Akonadi does not work, it should defintely not segfault.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
