Reproducible: Always

Steps to Reproduce:
1.Go to the Muon Software Center
2. Double Click on it (I have my mouse settings to doube click)
3. The box for Muon pops up but it is empty and then it crashes.
Actual Results:  
Muon crashes and asks if I want to submit a bug report.

Expected Results:  
It should have given me a listing of what I can install.

The first time it crashed, some issues happened with KDE. The file manager threw up an io-slave error and the program menu was empty. A restart fixed it and it did not happen on the second crash.
