It actually seems to be a software-properties bug that wasn't visible before the latest python-apt change.
Since the last python-apt upload, most "templates" now exist twice, once for binary entries, once for source entries.
software-properties shouldn't show all of them twice. I have a small patch for this that I'm testing now to make sure we don't get a different behavior from what we had in 10.10.
Closing python-apt task as it's not a python-apt issue. software-properties ask python-apt for all existing templates and that's indeed what it receives.
