Application that crashed: plasma-desktop
Version of the application: 0.3
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-17-generic i686
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
I'm using 4 virtual desktops.
Dolphin and Firefox were opened in different desktops.
I tried dragging a HTML file to firefox.
Unfortunatly, firefox had several windows and so, was "groupped".

I was unable to select which firefox window open my file with when, suddenly (Can a bug appear diffently ?) the bug occured.

Sorry if it's a duplicated one.
