Migration 0005 fails with django-jsonfield 0.9.13

[remcogerlich]

I have a site (the upload server) that uses lizard-map 4.51 and django-jsonfield 0.9.13.

When I run migrations on an empty database, lizard-map's 0005 migration crashes with "ValueError: No JSON object could be decoded".

I suspect some JSONField doesn't have a valid default in this migration, but I'm not going to fix it now.

My guess: during the 0005 migration we didn't use django-jsonfield yet and there was a different (perhaps at the time build-in) jsonfield in use. Weird that this is the first case were we see the problem.
