Application: muon-installer (2.0.65)
KDE Platform Version: 4.11.1
Qt Version: 4.8.4
Operating System: Linux 3.11.0-8-generic x86_64
Distribution: Ubuntu Saucy Salamander (development branch)

-- Information about the crash:
- What I was doing when the application crashed: Just upgraded to 13.10 and restarted the computer after installation.  Opened Muon software center and started to type in the search when I got a bug report.

- Unusual behavior I noticed: Previous to installation my computer changed.  It almost looks like it changed from 64bit to 32bit just because all the icons are larger and fuzzy looking.  I upgraded hoping it would fix the issue but it did not.  I'm not sure if this is what help cause the bug report though.  It may be a totally separate issue.

-- Backtrace:
Application: Muon Software Center (muon-installer), signal: Segmentation fault
