22319	ValueError: Related model cannot be resolved	efrinut@…	nobody	"Hey!

When I try to migrate comments model I get an error:

{{{
    raise ValueError('Related model %r cannot be resolved' % self.rel.to)
ValueError: Related model 'links.Link' cannot be resolved
}}}

It only happens for this model so when I remove Link fk everything passes smoothly
