[mythtv] Backtrace: Goom segfaults

[Carl Alexander]

Yes, that may fix the crash at that point, but the question is *why* is 
it going wrong?  What is the design or implementation inconsistency that 
is causing this? I haven't groked enough of the code to answer that.

has anyone valgrind'ed the code? Maybe a UMR or a over read is filling 
some of the variables with garbage data.
