[mythtv] Bug Report: Mythepg 's death as a result of 640x480

[tarek Lubani]

Hey guys!

I've generated a more comprehensive backtrace as per Isaac's instructions, 
and have noticed a few more things:

1) The mythepg problem goes away when theme.txt is set to 800x600.. It 
ONLY exists when I am in 640x480 (which I try to always be, since there 
aren't those black bars on the side when I'm in 640x480). 

2) This problem is *independent* of which "theme" is selected (liquid, 
blue, etc).

3) Backtrace:
