Application: korgac (4.10.5)
KDE Platform Version: 4.10.5
Qt Version: 4.8.4
Operating System: Linux 3.8.0-27-generic x86_64
Distribution: Ubuntu 13.04

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

KOrganizer was running in the background.  I had just started Firefox and it was re-loading its tabs; I clicked on the software updater icon to see what that was lit up for and got a dialog box saying the KOrganizer reminder daemon had crashed.

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