[mythtv-users] Abrupt mythfrontend crashes with trunk version?

[nospam312]

For the past 2 or 3 weeks mythfrontend has been abruptly exiting when
playing back recordings/LiveTV.  Does anyone know if this is a known
issue or how I can try to find out what the problem could be.  It can
sometimes do it several times in five minutes or it can be hours .  I
am using Mythbuntu 7.10 with the latest trunk autobuild.  Thanks.
