This very strange.  I started mythbackend and let it run.  EIT crawl 
stared after 5 min and reported a segfault.  A recording is still 
playing with an overlay saying that MythContext cannot connect.  At one 
stage I could select any one of the latest 10 or so recordings to play, 
but now there's only the 'Could not connect' box.

On restarting the backend it looks likely to repeat the sequence.
