[mythtv] Backtrace: Goom segfaults

[Ed Wildgoose]

I like the new goom (at least I think its different from before?).  
However, it seems to be segfaulting on me after a few mins of listening.

Backtrace is mostly useless (because it's compiled without debugging 
info), but shown below for reference.   Recompiling with debug info and 
of course the darn thing is stable... Any pointers to compile this up 
with the MMX stuff under the debugger?

Just out of interest, is anyone NOT having problems with goom?  (Just to 
get a handle on whether it's specific to my setup in some way)

Thanks for any pointers on tracking this one down

Ed W
