[MarcRandolph <mrand@xxxxxxxxx>]

Howdy, and thank you for helping to improve Mythbuntu by opening this
ticket. Unfortunately, through no fault of your own, attached stacktrace
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 if you can
reproduce the issue, so I'm going to close this ticket.
