Thank you for helping to improve Mythbuntu by opening this ticket.   The general launchpad policy is to leave bugs marked as private until the core dump has been removed, which I have now done.
Unfortunately, this backtrace attached is not useful to the developers. Could you please follow the "basic backtrace" directions outlined here:

http://www.mythtv.org/wiki/Debugging#Debugging_with_Ubuntu_packages

The above process should result in a new ticket being opened, so I'm
going to close this one.
