Application that crashed: kpackagekit
Version of the application: 0.4.2
KDE Version: 4.3.1 (KDE 4.3.1)
Qt Version: 4.5.2
Operating System: Linux 2.6.30.8-64.fc11.i686.PAE i686
Distribution: "Fedora release 11 (Leonidas)"

What I was doing when the application crashed:
Was logged into KDE as root (sorry needed to), KPackagekit automatically started. I noticed it was reporting gathering dist. upgrade information as well as some bug fixes. 

Tried to appoly them and application crash occurred.

Tried to then open KPackagekit and install rss-screensavers and crash occurred again.

No problems so far when logged in as a regular user
