Description
I'm testing OSX builds using Matt Terry's build grid. All the matplotlib builds are giving multiple errors like this:
======================================================================FAIL: Failure: AssertionError ()----------------------------------------------------------------------Traceback (most recent call last): File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/nose/loader.py", line 284, in generate for test in g(): File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/testing/decorators.py", line 152, in test baseline_dir, result_dir = _image_directories(self._func) File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/testing/decorators.py", line 303, in _image_directories assert mods.pop(0) == 'tests'AssertionErrorSee:https://s3.amazonaws.com/archive.travis-ci.org/jobs/30794968/log.txt
It's not clear where the failures are coming from, but this is an excerpt from the stdout of the tests.

python ../matplotlib/tests.py -sv --processes=8 --process-timeout=300Running in single process mode gives no failures. Does anyone have any idea how I could investigate further?
