Tvheadend

I've compiled it from git today and started testing it, then had this error every time:

After successfully adding DVB Network by location, and after waiting for all services to be detected, as soon as I click on "Map DVB services to channels" tvheadend crashes with this log:

I'm testing it on a fresh Ubuntu Server 12.04.1 install: {{{
$ uname -a
Linux tvheadend 3.2.0-30-generic #48-Ubuntu SMP Fri Aug 24 16:52:48 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
}}}
I've compiled it on another similar machine.

My DVB device is detected as _dev_dvb_adapter0_Fujitsu_mb86A20s, and in fact it's a Kworld UB430-AF (USB).

Please let me know any other necessary information.
