New crash information added by DrKonqi

kaffeine (1.1) on KDE Platform 4.5.1 (KDE 4.5.1) using Qt 4.7.0

- What I was doing when the application crashed:
Allways if I using Mobile Broadband Kaffeine DVB-T crashs. The DVB-T receiver is a a external USB CINERGY-T device and is located in about 1m difference to the Mobile Broadcast adapter and antenna. The DVB-T antenna is about 1,5m away.

I known that I can get pixel because of high frequency interferences. But theare is no reason to crash. This problemem occurs after going from Ubuntu 10.4 to 10.10. With Ubuntu 10.4 I had no kaffeine crashes.
