Enricher doesn't work on models with inheritance?

[lggwettmann]

Hey guys,

Some of the fields in my feeds don't get enriched if the target field points to a class that has been inherited. For models with inheritance, the PK is a one-to-one field. I don't know why but this line in enrich.Enricher._inject_objects() doesn't return an integer for the PK. Instead, the f_id stays a string which of course makes finding it impossible later on.

 f_id = model._meta.pk.to_python(f_id) 

I found that a simple cast to an integer works:

f_id = int(model._meta.pk.to_python(f_id))

Is this a bug? Could you check that and if possible push it? Thanks in advance.
