This should be fixed in SVN now...

I can't figure out what is wrong from the backtrace, but
I'll do some extensive testing with my PVR card.

I've only tested "R" in LiveTV with the HD-3000.
But I have a PVR in my other machine....

Is this the log for a PVR-x50 card or a frame grabber? Perhaps
this explains the segfault too...

We like testers that provide clear logs and 
simple test cases around here. :)
