Open Stack

Hi,

I noticed I can now run the pep8 tests like this (taken from Jenkins job):
	tox -v -epep8
	...
	pep8: commands succeeded
	congratulations :)

But the old way to run tests seems to fail:
	./run-tests.sh -p
	...
	File "/home/johngar/openstack/nova/.venv/local/lib/python2.7/site-packages/pep8.py", line 1220, in check_logical
	    for result in self.run_check(check, argument_names):
	TypeError: 'NoneType' object is not iterable

Is this expected?
Did I just miss an email about this change?

Cheers,
John
