Public bug reported:

I get eight test failures on Python 2.4 with the tests for
AsynchronousDeferredRunTest like this:

======================================================================
FAIL: testtools.tests.test_deferredruntest.TestIntegration.test_runner(AsynchronousDeferredRunTest, Success)

Traceback (most recent call last):

  File "C:\bzr\testtools\testtools\testcase.py", line 384, in assertThat
    self.fail('Match failed. Matchee: "%s"\nMatcher: %s\nDifference: %s\n'
AssertionError: Match failed. Matchee: "['setUp', 'test', 'tearDown', 'clean-up']"
Matcher: Equals(['setUp', 'test', 'tearDown'])
Difference: ['setUp', 'test', 'tearDown'] != ['setUp', 'test', 'tearDown', 'clean-up']

Basically cleanups aren't being called as
AsynchronousDeferredRunTest._run_cleanups uses
twisted.internet.defer.inlineCallbacks which needs PEP 342 so is Python
2.5 or later only.

I'm not sure if it's a general problem that the underlying exception is
being swallowed, but it's like:

Failure instance: Traceback: exceptions.AttributeError: 'generator' object has no attribute 'send'
C:\Python24\lib\site-packages\twisted\internet\defer.py:186:addCallbacks
