What version are you running?
1.7.x tip
What's the URL of the page containing the problem?
http://127.0.0.1:8080/admin/db/reviews/group/
What steps will reproduce the problem?
It's possible to create multiple groups with the same name when local_site=None, despite the unique_together constraint.
What is the expected output? What do you see instead?
This should not be allowed, since multiple groups with the same name break when we expect a single result.
What operating system are you using? What browser?
Doesn't matter.
