[mythtv] r7396 backend crash log

[Jack Hyde]

Trying to get a backtrace of this, but gdb keeps segfaulting on this crash.
I think this involves the thumbnail generation, but not 100% sure, I haven't
been able to figure out the pattern. This is on a slavebackend with firewire
and a QAM pcHDTV3k setup, the main backend has two pvr250 cards. It crashed
while recording off the firewire, though it also crashes off the QAM card
too. 2353_20051006010000.mpg is the partially recorded firewire stream.
