 There are at least two open tickets related to this that may be duplicates
 or warrant concurrent investigation: #9422 and #17587. By the way, it's
 easier if you open your PR against master and let the committer backport
 from there.

 Thanks. Problem seems to be having a FK to an object with a UUID pk.
 Attaching a failing test for Django's test suite.

Comment (by timgraham):

 I created a custom user with UUID pk:
 {{{
 import uuid

 from django.contrib.auth.models import AbstractUser
 from django.db import models


 class UUIDUser(AbstractUser):
 id = models.UUIDField(primary_key=True, default=uuid.uuid4)
 }}}
 And then tried:
 {{{
 python manage.py dumpdata uuiduser.UUIDUser
 [{"fields": {"username": "tim", "first_name": "", "last_name": "",
 "is_active": true,
 "is_superuser": true, "is_staff": true, "last_login":
 "2015-02-11T19:01:02.747Z",
 "groups": [], "user_permissions": [], "password": "...", "email":
 "a...@g.com",
 "date_joined": "2015-02-11T18:55:33.572Z"}, "model": "uuiduser.uuiduser",
 "pk": "dd100fcd-a894-4435-ad30-bdcd4671ac44"}]
 }}}
 Tested on SQLite and PostgreSQL. Could you provide more details? I'm also
 attached a test for Django's test suite that I tried writing to reproduce
 the issue.
