This appears to be mostly resolved by removing the 0.25 lib that was
left over after the upgrade so the problem seems to be more related to
the upgrade rather than myth iteslf

Title:
  mythfrontend.real crashed with SIGSEGV when starting the second
  playback

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  New

Bug description:
  I'm having a problem where the frontend is crashing when I attempt to
  play back a second recording.  The first recording plays back fine but
  the next time I try I get a segmentation fault.  The last entry in the
  log was audio related so I have tried another log with -v audio.
