Yeah, the Ubuntu guys make it nice and easy to debug.  I was hoping the 
Debian packagers did similarly.  I'll let you decide whether to go to 
the trouble of uninstalling Myth completely (get rid of all the packaged 
installation stuff) and then compiling Myth from source with the proper 
debug (or profile) compile-type and running it under gdb to see the 
totally new build of mythtv will still segfault.  And, if you want to go 
back to the packaged versions, you should really create your own debug 
package...

Also, it's possible that it's not so much a segfault as an OOM killer 
thing due to memory leaks (there seems to be one or more in some of the 
EIT-related code).  If that's the case, the backtrace wouldn't be very 
useful (though a valgrind report created with a profile compile-type 
would be).

However, I'd think that changing your system over to Ubuntu might be 
easier than doing all you need to do to get a good debug/profile build.  ;)
