Well, I have no idea.  I was getting these when I ran nosetests 
enthought/mayavi/tests enthought/tvtk/tests
and combinations of the above.  However, this is completely 
non-reproducible.  Right now, with python setup.py test, everything 
except one test passes -- here is the output:

[...]
ok
Failure: ImportError (No module named test_support) ... ERROR
Is the default PipelineInfo class built right. ... ok
test_tvtk_dataset_name 
(enthought.mayavi.tests.test_pipeline_info.TestPipelineInfoTest) ... ok

That looks like a problem with test_csv_sniff.  Otherwise everything 
else runs.  Weird.  Now running nosetests also works with just this one 
error.  However, if I do this:

$ nosetests enthought/tvtk/tests enthought/mayavi/tests

I get this:

[...]
Ran 184 tests in 35.844s

FAILED (errors=36, failures=2)

With the errors you have reported.  My guess is either the TVTKBase 
class is reloaded or the tvtk_classes.zip file is reloaded (since the 
zip file is added to the path)  and this causes the problem with 
"unbound method __init__() must be called with TVTKBase instance as 
first argument".
