22518	Migrations broken with custom user model	Stephen Burrows	nobody	"This is *not* the same bug as #22325, though it may be related. Also related to #22397 (in that the fix there caused this bug to appear).

I only know this is related to custom user models because migrations work fine if I remove the setting (and convert the custom user model to a normal model) and *then* generate and run them.

To reproduce:
1. Make an app with a custom user model and a few migrations
2. Remove all references to `migrations.swappable_dependency(settings.AUTH_USER_MODEL)` as a workaround for #22325
3. Migrations fail.

If that doesn't work, or if you'd like to skip that step, you can just use https://github.com/littleweaver/django-brambling@e6f9b24f69d56c1a33a3c737596690b685c3a68a

The migrations fail like this:

This bug exists in stable/1.7.x and master. I've already tried re-generating the migrations."	Bug	closed	Migrations	1.7-beta-2	Normal	duplicate			Unreviewed	0	0	0	0	0	0
