Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.3
Operating System: Linux 2.6.30.9-96.fc11.x86_64 x86_64
Distribution: "Fedora release 11 (Leonidas)"

What I was doing when the application crashed:
I was reading wikipedia on web snippet plasmoïd, i clicked a link, the new page loaded, then I did not do anything (well... I was drinking a coffea away from keyboard) then plasma crashed (plasma stopped, restarted and ask me to fill this bug).

I've repeted the same things again and the bug did not happened, so it's seems to be random (or maybe related to coffea ;) ).
