[Jonathan Lange <jml@xxxxxxxxx>]

Turns out this is due to bad interaction between the band-aid for bug
425113 and testtools.

Title:
  When running Twisted tests, failures are not reported

Status in Launchpad itself:
  In Progress

Bug description:
  With this basic test case:

  {{{
  class TestBlah(TestCaseWithFactory):
      run_tests_with = AsynchronousDeferredRunTest.make_factory(timeout=10)
      def test_failing_test(self):
          self.assertFalse(True)
  }}}

  I don't see a failure reported.  Tracing through the code in pdb I can
  produce a "AttributeError: "can't set attribute"" at the backtrace
  below:
