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 2.6.31.4 x86_64
Distribution: Debian GNU/Linux testing (squeeze)

What I was doing when the application crashed:
Error message occurs while logging into KDE upon startup. Full desktop appears shortly, then crashes and a black screen appears. I am using Debian squeeze.

Note: The crash is user specific. I created a test-user and could log into KDE without further problems.
