11082	Deadlock when entering LiveTV	Kenni Lund [kenni a kelu dot dk]		"I'm seeing this deadlock regularly after upgrading to pre0.26 from 0.25-fixes. This time I got a chance to attach gdb to the mythbackend process and collect a backtrace before restarting it. Unfortunately I didn't get the frontend backtrace as it didn't have any symbols installed.

Symptom: When I enter LiveTV on a frontend, the screen remains black with no sound and no error messages of any kind.
Performing a tcpdump on the frontend reveals that no data are received from the backend at this point. Looking at the backend reveals that the backend happily records from my HDHR to a LiveTV file, but it doesn't stream anything to the frontend.

I can exit back to the main menu with no issues and start LiveTV again afterwards, again resulting in a black screen and the backend recording to a new LiveTV file and not streaming anything to the frontend.

The backend log doesn't contain even a single line from the moment when I trigger LiveTV on the frontend. The frontend does produce log-entries, but no obvious errors are given (see attached file).

Restarting the backend fixes the issue.

I don't mind compiling a debug build or running with specific verbose options if needed - just ping me.
