The Python serializer's handle_fk_field() method now no longer handles the case where a related object is None and natural keys are in use. The problem appears to have been introduced in this changeset:

The code now no longer checks to see if the related object is not None before attempting to call natural_key() on it.

Upon inspection this appears to be a regression therefore marking as release blocker. I don't supposed you have a test?

In [17685]:

Fix #17879: Corrected regression in python (inherited by yaml and json) serializer that prevented serializing model instances with null FK ref to a model when serializing with natural keys. Thanks danfairs and tmitchell.
