[MarcRandolph <mrand@xxxxxxxxx>]

Howdy, and thank you for helping to improve Mythbuntu by opening this
ticket. Unfortunately, through no fault of your own the backtrace
attached is not useful to the developers. Could you please update to the
latest version of the debug packages by following 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.  Thank you!
