Bug 280747

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-8-generic x86_64
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed:
I right clicked on the KAlarm icon and chose quit.  A dialog opened up and asked me to confirm.  I chose yes (don't ask again) but the icon remained in the system tray.  I right clicked on it again and Plasma crashed.  I'm not sure if the second right click had any effect or if it was just taking a while to crash.

-- Backtrace:
Application: Plasma Desktop Shell (plasma-desktop), signal: Segmentation fault
