[mythtv] Recording/scheduling thread dying?

[Dave Just]

Has anyone else noticed their backend stopping recording scheduled  
programs after running for a while?  Also failing to respond to  
changes in the schedule, so e.g. setting a program to record does not  
highlight it in the guide or enter into the list of scheduled  
programs seen by the frontend.  Restarting mythbackend resumes normal  
behaviour, starting recording properly and displaying schedule  
changes.  Anyone any ideas?

I'm seeing this in svn 9799, but this has been happening in head  
versions for about two weeks.

I couldn't see anything in trac, so I ask the paranoid question of a  
cautious bug reporter (& even more cautious bug hunter): "is there  
something really wrong or is it maybe just me?"
