Bug 326450

Application: muon-installer (2.0.65)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-12-generic x86_64
Distribution: Ubuntu 13.10

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

Open Muon, search for "retext" for example and after a few seconds (3 or 4) it crashes. I've tried several times, and it always crashes after some time, doesn't matter what I do really.

The crash can be reproduced every time.

-- Backtrace:
Application: Centro de software de Muon (muon-installer), signal: Segmentation fault
