Your original patch for the backend file is not needed. With 1.6
the database backend is in the config.ini file for the tracker.

I did incorporate your patches to roundup admin to use _get_choice
(after removing a line that uses name.title() which doesn't exist).

I also removed access to the -f flag from the command line.
I have driven roundup_admin from shell here scripts and other
automation mechanisms, so I don't think -f is required at the
cli.

The test you supplied works fine.
