Bug 277543

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:

Browsing the internet and chatting with my friend with pidgin. Crash happened when Amarok switched to the next song, so I suspect it could be related to plasma notifier.

-- Backtrace:
Application: Powłoka pulpitu Plazmy (plasma-desktop), signal: Segmentation fault
