 in playback, mythfrontend is crashing out apparently when parsing CC708
 content (CEA-708(?))

 I've attached a gdb.txt output as well as what 'nohup' outputs from
 starting mythfrontend from the command line.  the mythfrontend.debug.log
 file has been abbreviated since it was approximately 1 million lines long.
 I edited out all of the content preceding where the start of the main
 playback loop.

 mythtv at mythtv2:~$ mythfrontend  --version
 Please attach all output as a file in bug reports.
 MythTV Version   : v0.25pre-1796-gd3243cb
 MythTV Branch    : master
 Network Protocol : 65
 Library API      : 0.25.20110414-3
 QT Version       : 4.7.2
 Options compiled in:
  linux debug use_hidesyms using_alsa using_backend using_bindings_php
 using_dvb using_frontend using_libxml2 using_lirc using_mheg
 using_opengl_video using_qtwebkit using_v4l using_x11 using_xrandr
 using_xv using_bindings_php using_mythtranscode using_opengl using_vdpau
 using_ffmpeg_threads using_mheg using_libxml2

 compile was done with make distclean first, and /usr/local/mythtv (my
 install prefix) was completely wiped out before install.

 my invocation from .xinitrc is:  gdb mythfrontend -x gdbcommands

 my gdbcommands file:
 handle SIGPIPE nostop noprint
 handle SIG33 nostop noprint
 set logging on
 set pagination off
 set breakpoint pending on
 break qFatal
 set args -l mythdebug.log -v all
 thread apply all bt full
 set logging off

 please let me know what I've missed or should do differently with this
 submission, it's only my second bug report to Trac  :)  thanks!
