Application: polkit-kde-authentication-agent-1 (0.99.0)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.4
Operating System: Linux 2.6.42.3-2.fc15.i686.PAE i686

-- Information about the crash:
- What I was doing when the application crashed:

I had just run sudo package-cleanup --oldkernels --count=1
When the command completed I opened kpackagekit
I went to "settings"
I de-selected some unnecessary repos (adobe, google-chrome, google-testing)
segfault occured

The crash can be reproduced some of the time.

-- Backtrace:
Application: PolicyKit1-KDE (polkit-kde-authentication-agent-1), signal: Segmentation fault
