Application that crashed: kpackagekit
Version of the application: 0.4.2
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-21-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
kpackagekit crashed after selecting all packages to update and pressing ok to start the process. Looks like the update process remained active in the background and succesfully upgraded some packages but not all of them.

 -- Backtrace:
Application: KPackageKit (kpackagekit), signal: Segmentation fault
