[mythtv] Mythbackend CVS Coredump

[Brian Foddy]

Hi, my dual CPU machine again...
Using a CVS capture from this Saturday I've seen 2 core dumps
with mythbackend.  I have 2 cards, both recording and
both set to start new programs at the same time. 
ie:  both recording 2 different 5:30 shows, both set to
start a new different 6:00 show.
One core seems reliable, the other questionable.  ALso, I 
don't think this core is new, I saw it in previous cvs', but
didn't have it built with -g or capture a core dump.

The bt is attached.  Seems to be inside or the calling of QString.

Quick review of my machine:
Dual Pentium 2 - 450
500MB ram
2 Hauppauge 401 cards
Ea capturing at 640x240

I love the work you've done so far.  I have the core so
if you need more info I can forward it.

Thanks,
Brian
