Application that crashed: kpackagekit
Version of the application: 0.4.2
KDE Version: 4.3.4 (KDE 4.3.4)
Qt Version: 4.5.2
Operating System: Linux 2.6.32-020632-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
KPackageKit (in autoupdate mode) craches after clicking OK button to apply updates. Cannot reliably reproduce, as it worked fine on the next attempt, after restarting through the KDE crash handler.

Using Kubuntu 9.10 x64, KDE 4.3.4
