[mythtv-users] FC5 crashing with newly installed 0.20

[Jay Bradley]

Just updated mythtv to 0.20 yesterday and have had a few crashes 
already. These happen overnight whilst the machine is left on for 
recording. I've no idea why this is happening but this is the tail of 
/var/log/mythtv/mythbackend.log

Hope somebody has seen something like this before and has some advice. 
I'm at a complete loss myself. Will need to set off on some serious 
google hunting to find more information.

Cheers, Jay
