Sorry, can't help (as I don't know *buntu), but once you figure it out,
it would be great if you could incorporate the mythtv-specific
instructions for getting package-based debug symbols for *buntu at
http://www.mythtv.org/wiki/Debugging#Debugging_with_Ubuntu_packages . 
(If you document both the MythTV package information and the Qt package
information, that would be ideal.)

Thanks,
