22411	Migrations attempt to create content types without first running contenttypes sync/migrations	Stephen Burrows	nobody	"If I am (for some reason) just migrating a single app on a fresh database, Django will try to create contenttypes for the app's models. But since it hasn't actually synced the contenttypes app yet, the creation fails. While this doesn't seem to affect the actual state of the migrations, it is startling and confusing, and seems unnecessary. I'm not sure which would be better:

1. Always migrating contenttypes before trying to create.
2. Only trying to create if contenttypes has already been migrated.
