If kwargs[field.name] is None, rel_obj is set to None, val is not set at all, and we get an UnboundLocalError at line 226. Context: the model in question had a OneToOneField whose primary_key was not yet set/was set to None and a save() was attempted.

See stacktrace at dpaste: http://dpaste.com/74655/

Either we need to have a better error-message here, for instance mentioning what field is the problem and how it can be fixed, or the code needs to do something sensible."		closed	Core (Other)	dev		invalid	models, onetoonefield		Unreviewed	0	0	0	0	0	0
