-- Information about the crash:
- What I was doing when the application crashed: I was doing nothing. After system's start, KPackageKit was search for the new updates and has been hung in the commit state mode. Therefore, this situation is reproducible every time after start up.

- Unusual behavior I noticed: KPackageKit hung and crashes after searching for updates.

The crash can be reproduced every time.
