14366	Model.objects.none().values(...).anything() is broken	Carl Meyer	nobody	"There's a bug in the interaction of EmptyQuerySet and ValuesQuerySet; chaining .none() with .values() and then following that with any QuerySet method that causes a clone results in ""AttributeError: 'ValuesQuerySet' object has no attribute 'field_names'"".

(Obviously this chain is useless in the simple case, but the utility of .none() is for methods that need to return a QuerySet but in some cases should return one with no results; this can easily break in such cases if the caller of that method does further processing the returned queryset that includes .values())."		closed	Database layer (models, ORM)	dev		fixed			Ready for checkin	1	0	0	0	0	0
