inspectdb errors: missing 1 required positional argument: 'collation'

[Stephan van Beerschoten]

I'm trying to recreate my models using inspectdb, but for some reason I'm now getting this output in my file:

from django.db import models

# Unable to inspect table 'AAA'

# The error was: <lambda>() missing 1 required positional argument: 'collation'

# Unable to inspect table 'BBB'

# The error was: <lambda>() missing 1 required positional argument: 'collation'

What's going on here? 

Thanks,

Stephan
