Bug 269492

Application: plasma-desktop (0.4)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10

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

First time was when i had grandfathers clock and amarok open, plasma just crashed. Second time closed down amarok to try and reload playlists which might have caused plasma to crash and also amarok. Just installed 4.6 updates to system

The crash can be reproduced some of the time.

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