[mythtv] Mythtv 0.23 RC Segfault in Mythfrontend

[Steve Berlo]

Hello all,

I just upgraded to Mythtv 0.23 and am getting a segfault when I attempt to
watch any recordings or videos.  Here are a few things I have tried in
troubleshooting:  Since there were audio changes in this release, I have
tried setting audio to NULL, I have tried several of the different video
output profiles and methods, and several different recordings (I have an
HD-PVR, Air2PC, and PVR-250, and all of the recordings have the same results
when I attempt to play them), I am running the current version of the NVidia
drivers from their web site - I just tried the newest
NVIDIA-Linux-x86_64-195.36.15-
pkg2.run, but previously I was running 190.53 and had the same symptoms.

The backtrace shows this segfault:

Program received signal SIGSEGV, Segmentation fault.
0x0000003a7d86ca2c in QMutex::lock() () from /usr/lib64/libQtCore.so.4

(I can email the whole backtrace file and mythfrontend logs if necessary -
they are too large to post to the list)

I am running on Fedora 12 x64 on AMD (I have another system that is running
Fedora 12 x32 on Intel - same symptoms)

Here is some system info that might be relevant:
