Possible bug in Django 1.7a2 Migrations -- cannot create foreign key to proxy model

[br0wnbay]

Hi Everyone, 

I know I was able to do this before in Django 1.6, but I don't seem to be able to create a foreign key pointing to a proxy model. 

I've created a couple of StackoverFlow posts, but haven't had much help.

Here's a Git repo of a simple sample project that generates the error when you try to run migrate.

I've been testing this against Postgres (9) with Django 1.7a2  (commit 834d78ffc3a7 (newer commits haven't addressed the issue))

Any help would be appreciated. 

Thank you.
