[mythtv] mythfrontend crash when recording ends/begins

[Joseph A. Caputo]

I've seen the following crash:

-Scheduled recording begins 20:00-22:00, second recording scheduled for 
22:00-22:30
- Start watching 1st recording in-progress about an hour in
- At 22:00, mythfronted crashed while watching the first recording as the 
second started.

This is with CVS from 5/04.  I'll try to get a backtrace tomorrow, then I'll 
try current CVS.  In the meantime, maybe someone else can reproduce this.
