Bug 327933

Application: korgac (4.11.3)
KDE Platform Version: 4.11.3
Qt Version: 4.8.4
Operating System: Linux 3.11.0-13-generic x86_64
Distribution: Ubuntu Trusty Tahr (development branch)

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

I don't interact with KOrganizer. It is simply running in the background within Kontact while I'm working on my machine. This crash occurs randomly.

-- Backtrace:
Application: KOrganizer herinneringsdaemon (korgac), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
