It certainly looks like there's a bug there somewhere, but there's so much going on in your code (including inheriting from PolymorphicModel, a third-party base class) that it's hard to say where the bug might be (and whether it's even a bug in Django at all) without doing some direct exploration (i.e. using pdb to trace into the filter call and figure out exactly why a FieldError is being raised for 'slug' when a field of that name appears to exist). I think if you want a resolution here, you'll likely need to do that exploration yourself and try to narrow down the source of the bug so that you can reproduce it with a simplest-case example.
