[mythtv] BUG: Segfault on exit from live TV and recordings.

I update my mythtv about once every two weeks from CVS and about a month ago
(maybe less) I've been seeing a problem with exiting from LiveTV and
watching recordings. When I exit mythfrontend segfaults. I use GL sync and I
believe the problem lies in that. Below is output from gdb. And included is
my settings.pro file. Please let me know if anyone needs more information.
I'm also looking further.
My config is an Athlon 1ghz with an Nvidia 5600SE (Nvidia drivers 1.0.5336)
running SuSE 8.2.
- Mark.
