Application that crashed: k3b
Version of the application: 1.66.0
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2)) "release 139"
Qt Version: 4.5.1
Operating System: Linux 2.6.27.23-0.1-pae i686
Distribution: "openSUSE 11.1 (i586)"

What I was doing when the application crashed:
I installed the KDE 4 version of K3B and ran it once. I then opened a second instance of it and K3B crashed. Now I cannot start the application, it crashes before any windows are shown.

From previous experience, the bug reporting system did not record my distribution, so just in case, I am using OpenSUSE 11.1.
