19774	contentypes generic module has core functionality plus admins-specific one	Ramiro Morales	nobody	"(Copied from https://code.djangoproject.com/ticket/16368#comment:16)

The django/contrib/contenttypes/generic.py modules contains both the definitions of the model-related generic stuff (!GenericForeignKey, etc.) AND the admin app-related specialized inlines (!GenericInlineModelAdmin, !GenericStackedInline, !GenericTabularInline.)

So, for example, if you import `django.contrib.contenttypes.generic` from your models.py because you need !GenericForeignKey then the !GenericXInlineY sutff imports django.contrib.admin and it in its own turn imports contrib.sites causing the reported failure (see below). Again, the Sites framework isn't listed in INSTALLED_APPS and what is worse: The admin app isn't either (!).

Maybe it's time we move !GenericInlineModelAdmin, !GenericStackedInline, !GenericTabularInline from django.contrib.contenttypes.generic to, say, django.contrib.contenttypes.generic_admin? (of course this would need a deprecation process)
