Bug 276393

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-30-generic i686
Distribution: Ubuntu 10.10

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

1) paused amarok
2) blocked session (screen saver is blank screen)
3) leaved it for about 1,5 hours
4) returned from screen saver — amarok is hang and eating 50% of CPU
5) killed amarok from KDE utility couse closing didn't do anything
6) plasma crashed

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