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:
Sudenly Plasma crash.

One note that must be useful: I use 2 displays. The second one is a CRT and smaller than the main display. Every time I do a login the wallpaper on this second display is never loaded. I need to go to desktop setting and set the wallpaper. 

I hope this could be useful. Thanks!
