Bug 199269

Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.2.95 (KDE 4.2.95 (KDE 4.3 RC1))
Qt Version: 4.5.0
Operating System: Linux 2.6.28-13-generic i686
Distribution: Ubuntu 9.04

What I was doing when the application crashed:
Whe open something, it doesn't matter what tha plasma desktop crashes, it happens in verry random periods, but i think that its something connected with the GNOME apps, because it crashes mainly when i'm using a gnome app, eg. Mozilla, totem, exaile...
