Comment (by mochawich):

 The test you proposed will not fail because you checked for the wrong
 value

 {{{
  self.assertEqual(form.cleaned_data, {'array': ['', '']})
 }}}

 You should have checked for an empty array instead as in

 {{{
  self.assertEqual(form.cleaned_data, {'array': []})
 }}}

 Since all values are considered empty characters `remove_trailing_nulls`
 should result in an empty array. Not in an array that has empty values.
 Such an array doesn't pass the later check of the form here

 line 1188 db.models.base.py
 {{{
             # Skip validation for empty fields with blank=True. The
 developer
             # is responsible for making sure they have a valid value.
             raw_value = getattr(self, f.attname)
             if f.blank and raw_value in f.empty_values:
                 continue

 }}}
 In this case the `raw_value` is ['', ''] while it should have been
 trimmed.
