Application: kontact (4.8.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-29-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Shutting down the system.

Everytime I shut down or restart the system Kontact crashes, and my computer won't proceed with the shutdown.

- What I expect
Close Kontact without crashing, proceed with shutdown

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
