Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.3
Operating System: Linux 2.6.32-2.slh.3-sidux-686 i686
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
I have tried to drag the konsole icon from the menu (Favorites) into the panel. While dragging the icon the mouse cursor did cross the pager that is included in this panel. The pager did switch from desktop 1 to desktop 2 and further to desktop 3. (I have a 3x2 desktop layout.) While still dragging the icon plasma did crash. I tried it once again and could reproduce the crash.
