Application that crashed: kpackagekitsmarticon
Version of the application: 0.5.4
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.3
Operating System: Linux 2.6.31.12-174.2.3.fc12.i686 i686

What I was doing when the application crashed:
KPackageKit crashed while installing system updates completed.  I ran "yum upgrade" to check if KPackageKit had completed it's job.  It seems that all udates were performed successfully.  The crash seems to have occured after updates were complete and the program was rescanning for possible additional updates.
