Bug 305769

Application: kontact (4.9)
KDE Platform Version: 4.9.00
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:
open email with new event, click click on add event, kontact crashes
this happens always - it worked until some days ago, since then it is crashing all the time

The crash can be reproduced every time.

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