Thanks for the report. Is this the full traceback? It looks like there is something missing, but I'm not sure.

We saw that error in travis a couple of times. I am not entirely sure why that happens. It fails to download the datasets from mldata.org. But actually during the tests it shouldn't really try that and use a mock lib instead.... we'll have to investigate that a bit closer.
Can you give me your nose version?

@amueller all the errors seen in traceback are from doctests, so I ran nosetests -v --with-doctest on sklearn/datasests, there was no error. So I think introduction of test_home_data resolved the error. I am not sure though, what do you think?

Closing, since this is quite old and is likely not to be relevant any more.
