Application that crashed: kpackagekit
Version of the application: 0.4.0
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-server i686

What I was doing when the application crashed:
I just typed the name of the pack I was looking for and pressed "enter" and the KpackageKit closed. At the same time I was listen music with amarok and burning a ISO DVD with K3b. My notebook is a LG 405H Core2Duo 5750 with 2GB Ram. I use Kubuntu 9.04 with KDE4.3
