[mythtv] DVB mythfrontend crash with BT

I get the attached backtrace after a segfault using the latest CVS.
Procedure is to simply view an old recording. The preview of the recording
works fine, but as soon as I select it to play it it segfaults. I don't have
an analogue card to try at the moment, but it would appear it may happen
with others.
I'm not sure where to start looking right now, but I do remember some
mention of the playbox stuff changing. Also I had no issues
with compiling DVB support in as Isaac mentioned might happen in recent
commits.
This occurs on files that worked fine before my recent update (last updated
about 1 week ago). This is against current CVS.
