Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.6.0
Operating System: Linux 2.6.32.2-tp42-toi-3.0.99.44 i686
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
This crash happened after trying to restart plasma after the crash reported in 219671.

Well I guess both of those are duplicates of bug #219449. I will mark them as such when I have enough bugzilla karma.
