Application that crashed: kpackagekit
Version of the application: 0.4.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.28-15-generic i686
Distribution: Linux Mint 7 Gloria - KDE Community Edition

What I was doing when the application crashed:
Repeatable, but only started happening today. 
Selected two reccomended updates. There were 5 updates that were restricted, and not going to be installed. I checked the "+" button, then 'apply'. As soon as "apply' is pressed, the installer crashes. I refreshed and re-tried, and selected 'OK' as opposed to 'apply'. Same crash.
