Application that crashed: kpackagekit
Version of the application: 0.4.2
KDE Version: 4.3.1 (KDE 4.3.1) "release 6"
Qt Version: 4.5.3
Operating System: Linux 2.6.31.5-0.1-default i686
Distribution: "openSUSE 11.2 (i586)"

What I was doing when the application crashed:
I was running YaST2 at the same time and it always crashes when I run both together. This could proberbly be because they are both package managers. This bug is easily reproducable. first run YaST2 package manager then run kpackagekit
