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

After selectiong some packages to install, I wanted to controll the very ones by looking at "install preview". This worked fine.

When returning to previous view (where I can install) MUON crashed

The crash can be reproduced some of the time.

-- Backtrace:
Application: Muon-Paketverwaltung (muon), signal: Segmentation fault
