Bug 243582

Application: kpackagekitsmarticon (0.5.4)
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-23-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
KPackageKit changed behaviors on me, without my making that change.  It suddenly stopped notifying me about available updates and started to apply them automatically, instead.  I attempted to open the Software Sources, Updates screen to change it back to "Notify" only, but the update window was blank.  I closed KPackageKit and it crashed.  I tried three times and it crashed all three times.  It persisted after rebooting.

The crash can be reproduced every time.

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