django contenttypes post_sync breaking syncdb (again)

[mspang]

Got this error:

$ ./manage.py syncdb
Creating table auth_permission
Creating table auth_group
Creating table auth_user
Creating table auth_message
[...]

You just installed Django's auth system, which means you don't have any superusers defined.
Would you like to create one now? (yes/no): no

I didn't have django.contrib.contenttypes in INSTALLED_APPS at the time, but adding it made
the problem go away.

You say "again" in the summary as if this is a re-occurrence of a previously-fixed bug but give no pointers to any old bug like this. For those of us not around since day 1 or perhaps with not the greatest memories, it would be helpful if you actually identified any previous identical bugs.

As it is, as mentioned here: ​http://www.djangoproject.com/documentation/contenttypes/

the auth framework requires contenttypes. The syncdb output indicates you've got auth in your INSTALLED_APPs. Therefore you need contenttypes also. Since you didn't have it, you got an error. Adding contenttypes fixed the eerror. What's the problem?
