Bug 272380

Application: kontact (4.6 beta5)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.36-gentoo-r5 x86_64
Distribution (Platform): Gentoo Packages

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

In Kontact, I was adding a new event in its KOrganizer part. And when I tried to save, whole Kontact crashed.

I don't know if it has anything to do with it, but 10 minutes before that I restarted both Nepomuk and Akonadi daemons.

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