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 2.6.31.6-desktop-1mnb i686

What I was doing when the application crashed:
I filled in a form in Mozilla Firefox, it gave me back a receipt, i printed into a pdf-file, went to Dolphine to check, Okular started, the printing was correct, I shut down Okular and was met by a crash. What crashed? I do not know, but I think the word plasma was there somewhere.
