Any idea if I'm doing something wrong or if I'm running into a bug?
I added some fields to a model, and generated a migration.
When I apply the migration, the migrate command crashes, with both django
1.10.3 and 1.10.4.
I had a similar migration issue with another app in the same project, that
occured in django 1.10 and 1.10.3.
Is this crash a known issue/common pitfall?
Cheers,
Frankie
