Can you do a backtrace as described in the wiki/HOWTO (
http://www.mythtv.org/wiki/Debugging ).  We need the debug symbols (see
the info on using package-based installs in the wiki page and then fix
it up/add to it as you find more info) and need a "thread apply all bt
full" backtrace.

Thanks,
Mike
