application of migration fails

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
