Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-19-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I made some configs in try icon area. A while after the tasks were done, say a minute or less, I try to go back for reviewing those configs and Oops! al desktop seem crashing. In a second autorecover brings things running again when the bug reporting wizard pops up, and I'm here now ;)
