Phil,
The backtrace is missing symbols, meaning we're missing a lot of useful
information. It would be great if you could try again, this time after
installing MythTV debug symbols (or after recompiling with
--compile-type=debug or --compile-type=profile ).
There are some instructions for getting useful backtraces (and debug
symbols) at http://www.mythtv.org/wiki/Debugging (and, please feel free
to fix the Ubuntu portion as you figure out the details, if you're using
Ubuntu packages--or for that matter, adding to/cleaning up/improving the
info for whatever distribution you are using).
Thanks,
Mike
