14975	TransactionTestCases are broken by django.contrib.auth in 1.2.4	Randy Barlow	nobody	"I tried to upgrade my project to 1.2.4, and found that my TransactionTestCases were failing. I discovered that they would pass by themselves, but they would fail if I ran the django.contrib.auth tests first.

I made a very simple Django project that has an app with a single TransactionTestCase. It runs a self.assertTrue(True). If you run the testapp test by itself, it will pass, but if you run the auth tests first, it will fail in this way:

I put this into the Testing framework component, but it may be more appropriate in the Authentication component.

Django rocks, thanks for working on it!"		closed	Testing framework	1.2		fixed	blocker, regression		Accepted	0	0	0	0	0	0
