django-tagging not working in 1.1?

[nbv4]

I'm having trouble getting my tagged modles registered in 1.1

When I have "tagging.register(MyModel)" at the bottom, I get this
error when I try to add a new instance of that model in the admin:
"null value in column "object_id" violates not-null constraint"

In both cases, commenting out the register line makes it so both
aditing and creating new items work. Using the admin interface and
using save() via the interactive shell has the same result. Is this a
known bug in django-tagging, or is there something wrong with what I'm
doing?
