Update.  Another crash this morning.  My wife is not happy.  I
rebooted and it started working then the frontend crashed.  Now she is
really unhappy.  Does anyone know what is going on?

Again, I have Mythbuntu 8.04

I am posting the backend log from last night and the frontend log from
this morning.
