[mythtv] Myth .11 sometimes seeking causes hang and return to
previous menu - gdb attached

I get this problem with both the master backend and slave backend. When
I press the seek button, especially if i press it fast consecutively,
the show just hangs and eventually quits to the previous menu. To deal
with this, I press save position at the time of the hang, exit from the
screen and then select the movie again to go back to where I was
watching it. If I set seek to sticky keys, the error seems to be
reproduced at a specific point in the recording. I tried this under
gdb. When I encountered the hang, I killed mythfrontend and got the
outuput attached. Thanks.
