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

What I was doing when the application crashed:
desktop crashed when closing window - before it started to behave like no personalized configuration was made, just it used the deafult one

 -- Backtrace:
Application: Plasma Workspace (kdeinit4), signal: Segmentation fault
