It's not possible to remove a bugwatch from a product that started using Launchpad as its bugtracker.

I'd prefer not doing too much when flipping the switch to use Launchpad
as the official bug tracker. If someone experiements with that switch,
it'd be nice for them not to loose any data. It shouldn't be too hard to
make the update and delete code aware of the "official bug tracker"
switch.

I'm having the same problem with this bug.
