[Bug 1037290] Re: mythfrontend.real crashed with SIGSEGV when starting the second playback
This appears not to be resolved. A new bug( Bug #1038746 )was created,
sorry I couldn't see how to attach the data to this one.
I thought removing the errant libs had solved the problem but it appears
to have been coincidence.

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.
