-------------------------------------+-------------------------------------
 I have had a persistent problem with mythfrontend crashing during playback
 while in livetv or recorded playback.  This has been happening for many
 months.  I had been waiting to see if package updates (from rpmfusion)
 would include a fix for the issue, but the problem continues.  In fact, it
 seems to be getting worse.  It may only happen after a couple of hours,
 and other times this can occur repeatedly only minutes/seconds apart
 (frustrating trying to watch - resorted to running mythfrontend in while
 true loop).

 I have had mythfrontend running on other computers during this same time
 and I have not been experiencing the the issue in either of those cases
 (Fedora 14 and 16).  There are differences in these cases as I do not run
 mythfrontend continually and I don't run a backend on them.  The crash
 only seems to effect the the htpc (Fedora 14) connected to the TV and
 running the backend.

 I also noticed that there may be similar problems effecting mythcommflag.
 I saw this while looking at the mythbackend.log.  Since I started
 collecting coredumps I notice that I have one for mythcommflag to, so I'll
 include the backtrace for that also.

 Reproducing Problem:
 - Run mythfrontend
 - Watch livetv or recorded programs
 - Wait (happens during playback, not paused)

 I've installed updates as new packages have become available, so I'm
 attached a backtraces for each one.
