Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.71 (KDE 4.2.71 (KDE 4.3 >= 20090428))
Qt Version: 4.5.1
Operating System: Linux 2.6.29-1-686 i686
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
I have compiled kde from trunk (pre 4.3) and plasma is crashing in xnest. The display is also wierd. 
A screenshot of the display is also attached. I logged into failsafe terminal and run startkde manually.
