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

I was starting Muon and the program crashed immediately with an error, which implied that the /etc/apt/sources.list is malformed.

The crash can be reproduced every time.

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