django tries to rollback transactions on exceptions when using the dummy engine

[Ben Dean-Kawamura <ben.dean.kawamura@…>]

I'm using django, but don't want to use the database part of it. However, this causes a problem whenever I have an unhandled exception. At the bottom of django/db/init.py, django connects _rollback_on_exception() to the got_request_exception signal. This means that on every request exception, transaction.rollback_unless_managed() is called which fails. Note: I'm not importing the db module, but other django modules seem to do it.

I think the solution is to not hook up the callback if the dummy engine is in use.
