New crash information added by DrKonqi

kpackagekit (0.6.3.3) on KDE Platform 4.6.00 (4.6.0) using Qt 4.7.1

- What I was doing when the application crashed:

At first I've tried to install Open Arena. During the downloading of the package I was surfing the web for a while using rekonq. Several minutes have passed (~10 or so) and I've switched back to KPackageKit. The downloading was still at 16 % as it was before I had surfed the web. I've cancelled installation and application has crashed. Later I've intentionally reproduced the bug installing Tremulous. This time I haven't performed any actions after starting installation before cancelling it - just run -> authorize-> wait for 10-15 seconds -> cancel -> crash. I haven't made any other attempts to cancel downloading of the packages.

Hope this will help, good luck and thank you
