Comment:

 Looking at the gdb output the segfaults both occur in the same spot,
 however the code appears to have NULL pointer protection so something
 isn't quite right.

 However you say it sometimes will process the whole way through, and
 sometimes segfault. It's possible there's some memory corruption
 happening. Can you run the following

 valgrind --error-limit=no --show-reachable=yes --log-file=commflag-
 valgrind.log -v -- /home/km/svn-
 myth.qt4.new/trunk/mythtv/programs/mythcommflag/mythcommflag --force -f
 3842_20100617220000.mpg -v playback > commflag.log

 Please attach the output file commflag-valgrind.log to the ticket.

 Thanks.
