Bug 273930

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 was browsing the web using Chrome version 11.0.696.68 and plasma crashed, but did restart properly. The only other apps I had open was Kopete minimized to the system tray and Konsole. This is the 1st time Plasma crashed and I haven't been able to reproduce the problem.

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