 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
 run
 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!
