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

1. Go to System Settings
2. Open "Software Updates"
3. At the bottom the "Waiting for other tasks" progress runs "forever" (at least some minutes)
4. Press Cancel
5. It crashes

The crash can be reproduced every time.
