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 2.6.31-5.slh.2-sidux-686 i686
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
Whenever I start a KDE application, the desktop will crash. This time I gathered all dbg packages to get a 3 stars report. Hope it will help.
