[mythtv] frontend lockups while editing cutlist w/back trace

I was actually trying to get a backtrace of a different lockup event.
I normally run release instead of debug. This is my first backtrace
and I followed the documentation. I check the gdb website and it seems
the version I running (RH9 dist) is the latest. If this doesn't
provide the right info please tell me how to collect it.
What I was looking for: After editing the cutlist and returning to
playback the audio is gone. Sometimes skipping back (left arrow)
causes the audio to return. Other times the playback freezes before I
hit skip back.
I was skipping around in the cutlist using 10 min increment and the
frontend locks up completely. This never happened before. I just
updated cvs (sept 11 at 7:20 pm edt). I haven't recompiled without debug
to see if it does it with "release"
Anyway, here the backtrace. Let me know what else I can do.
Thanks,
Vinton
