Application: muon (2.2.0)
KDE Platform Version: 4.13.0
Qt Version: 4.8.6
Operating System: Linux 3.13.0-24-generic x86_64
Distribution: Ubuntu 14.04 LTS

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

I was installing the package "libalut-dev". Just after the package was completely installed, muon crashed. I could not see whether it had shown the list of packages again or not.

-- Backtrace:
Application: Gestore di pacchetti Muon (muon), signal: Segmentation fault
