18376	Model formsets apply unique checks to blank, null fields	Chris Adams	Joeri Bekker	This is similar to #13811 but applies to fields declared with ``unique=True`` rather than ``unique_together``: a model formset will incorrectly raise a ValidationError during ``validate_unique`` if more than one of the objects have a null value. I noticed this on a site using admin list_editable with a blank, null field but the problem appears to affect any model formset.
