Queryset raising EmptyResultSet exception (instead of being empty)

EmptyResultSet exception is fired in 'in' lookups, if the lookup is against an empty ValuesListQuerySet.
>>> ids = Tag.objects.filter(id__in=).values_list(id, flat=True) >>> Tag.objects.filter(id__in=ids)
ids is an empty ValuesListQuerySet, as expected. The second line raises EmptyResultSet exception, where I would expect an empty QuerySet instead.
