Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.5.1
Operating System: Linux 2.6.29-custom i686

What I was doing when the application crashed:
Selecting an item on the taskbar sometimes crashes the whole plasma. Sorry, didn't have more time to track this bug down. Creating this bug entry more as a reminder ;)
