The colormap functions seem all OK. But I got other errors irrelevant
to your update. I manually checked all images invoking errors, they
are all OK. Somehow, their file handles are not closed properly before
reopening.

Here is the test result:
>>> import nose
>>> print nose.__version__
0.11.4
>>> import PIL
>>> print PIL.__version__
>>> from PIL import Image
>>> Image.VERSION
'1.1.7'
>>> import matplotlib
>>> matplotlib.__version__
'1.0.0'
>>> matplotlib.test()
