Title: Frequently random Plasma crashes

What I was doing when the application crashed:
Since a week, Plasma is crashing randomly. Usually it crashes when the CPU is
heavily loaded. 
For example I'm compiling KDE from trunk and doing a lot of other operations...
I'm not able to find a pattern to reproduce the crash.

 -- Application and System information:
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: 4.5.0
Operating System: Linux 2.6.29-ARCH x86_64
