Bug 278642

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-10-generic i686
Distribution: Ubuntu 11.04

-- Information about the crash:
- What I was doing when the application crashed: amarok froze and i killed (not simply ended) the process when suddenly also plasma crashed

- Unusual behavior I noticed: amarok used 50% cpu, slow response to mouse-klicks

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