Bug 263822

Application: knotify4 (4.0)
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-24-generic-pae i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed: Started Amarok selecting a largue number of songs and clicking in open with amarok makes kwin crash when amarok starts. Tried 4 times more and same issue happens, maybe some update or setting is related to this.

- Custom settings of the application: Might be Settings>COnfigure Amarok>Notifications>ON-screen display. Not sure but might be related to that setting cause when i start amarok playing a song the notification pops up and I think that makes KDE to crush.

The crash can be reproduced every time.

-- Backtrace:
