Bug 296332

Application: kontact (4.7.3)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
In Kontakt I chose Ktimetracker. I tried to add a task (the first) in ktimetracker. Then ktimetracker and kontakt crashed.

The crash can be reproduced every time.

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