Bug 194414

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-11-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
desktop crash when start, like example kontact, amarok, kopete or firefox.  after restarts (by clicking windows crash restart option or automatically). That could be sometimes during a KDE Jaunty session.  

 -- Backtrace:
