Bug 210401

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.26.8.tex3 i686

What I was doing when the application crashed:
I was trying to switch between two Dolphin windows that were grouped on the taskbar, clicked on the grouping and that's when Plasma crashed.
