20382	random TransactionManagementError during tests in _fixture_setup	joao@…	nobody	"Automated Django 1.5.1 tests randomly fail with **TransactionManagementError**. It is hard to track down because a failed test can run again, without any changes, and pass.

I am NOT using the **@transaction.commit_manually** decorator and am aware of the need for manual commit/rollback when it is used.

One view does have the **@transaction.commit_on_success** decorator. It does NOT have any commands for manual commit/rollback and from the docs I believe this is correct. But this might be irrelevant:
1. the view is not called in every fail case
1. error raised during fixture setup

Test database is set to django.db.backends.sqlite3
