[mythtv] Mythepg's death as a result of mythfilldatabase failures

[tarek Lubani]

I have been playing around, and it is almost certainly not something 
missing in the database.. I've checked through it semi-carefully..

The seg-faults are consistent and very invasive.. They happen when i go 
from 100 to 865 backwards (100 is my first channel and 865 is my last).. 
And also at many times throughout, such as whenever 204 (CNNHN) shows up.. 
If, for example, I go to 205, then do mythepg, there is no segfault.. what 
else can cause mythepg to segfault? Here is a backtrace. This is just as 
relaible as the others, and happened when I went from channel 100 to 865 by 
hitting the up cursor once.:
