Bug Description
I found a bug in dvb-usb kernel module with "Hanftek UMT-010 DVB-T USB2.0" controller. The modules load without problems but if I start kaffeine for watching TV, the program crashes and the following messages occurs in /var/log/messages

Im running Ubuntu Feisty with kernel version 2.6.20-16-generic #2 SMP Sun Sep 23 19:50:39 UTC 2007 i686 GNU/Linux. The same controller works fine on a box with Ubuntu Dapper.

Sorry, this is the wrong section I see. :| Please remove that report. I'll file it to the Ubuntu project.
