[mythtv-users] Frontend segmentation fault

Hello,
When MythBuntu 9.10 (MythTV 0.22) on my ASRock ION 330 tries to
visualise a .MOV file in the MythGallery, the frontend crashes with a
segmentation fault. Playing the same .MOV file using mplayer works, even
though it complains about a few things. (log attached).
In an attempt to solve the issue, I went through all sorts of settings,
in "General", but also in the TV playback settings. Changing the
playback opsion from say "Normal" to CPU++, or any other does affect the
way it crashes, but it always does.
My question is how do I have to configure MythTV to correctly play back
.MOV file without crashing?
Many thanks for hints and help,
peter
