Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
Qt Version: 4.5.1
Operating System: Linux 2.6.28-13-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
It just crashed when opening dolphin but reloaded in few seconds
No blocking, no simptom, just a plain crash that magically recovered after few seconds

 -- Backtrace:
