Application that crashed: kpackagekit
Version of the application: 0.4.2
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-15-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
KPackageKit notifies me of updates.  I select the updates, then click OK.  I then get the the crash notification from KPackageKit.  However, KPackageKit is still downloading the updates via the KPackageKit Smart Icon.  This does not happen every time, but has happened more than once.

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