Application: kpackagekitsmarticon (0.5.4)
KDE Platform Version: 4.4.5 (KDE 4.4.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.32.23-170.fc12.i686.PAE i686
Distribution: "Fedora release 12 (Constantine)"

-- Information about the crash:
I use KPackagekit to perform the automated system updates from Fedora.  The system seems to work fairly well, but it seems that almost every time I -finish- with the application, and have closed it and moved on, a background process of some kind will crash 2-5-10 minutes later!  So I'm not actually -using- KPackagekit at the moment it crashes...

The crash can be reproduced some of the time.

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