Bug 332359

Application: kontact (4.12.3)
KDE Platform Version: 4.12.90
Qt Version: 4.8.6
Operating System: Linux 3.13.0-18-generic x86_64
Distribution: Ubuntu Trusty Tahr (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
after todays automated ubuntu upgrade kontact crashes on startup.
The wrapped applications (kmail, kaddressbook, knotes, ...) do not show any problem.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
