New crash information added by DrKonqi

muon-installer (1.3.0 "Daring Dalek") on KDE Platform 4.8.1 (4.8.1) using Qt 4.8.0

- What I was doing when the application crashed:

There were a couple of installs running in the background so it's hard to tell what crashed, but I was just clicking around in the GUI and boom.  From the look of the stack it's this bug, but am I running the fixed version or is this still a problem?
