Thanks for that pointer. I compiled a debug version of mythtv (still on
6857) and recreated the problem. Output of 'thread apply all bt full' is at
the end of this e-mail. I again noticed the frontend crashed at the moment
the backend starts a "Starting Commercial Flagging".
Not sure if is related, but when I stopped recording the program the
following was logged also by mythfrontend:
2005-07-21 13:22:24.705 Error: File
'/content/television_recording/1_20050721132200_20050721134500.nuv' missing.
I hope this provides enough information.
