-- Information about the crash:
- What I was doing when the application crashed:
I did nothing special, I just have my google calendar configured in KOrganizer, it's being refreshed every 10 minutes. I received a couple of notifications today from korgac and then suddenly it crashed. It happens every time, but I have no idea why, as I'm not doing a anything special with it.

The crash can be reproduced every time.

-- Backtrace:
Application: KOrganizer Reminder Daemon (korgac), signal: Segmentation fault
