Mox isn't playing well with nosetests on failures - OSX

[GoogleCodeExporter]

I'm not sure if this is a nose problem or a mox problem; but I thought I would 
share it here.

The problem is the readability of the error.  The error is being thrown because 
the mock isn't matching, which is good.  However, the error gives no clue as to 
what 
failed.  In OSX, I have no idea what mock getting the wrong data sent to it.

What steps will reproduce the problem?
1. Create a failing test that use mox
2. Run the tests with nose

What is the expected output? What do you see instead?
I expect to see output like:

======================================================================
FAIL: test_failing_hello (mymodule_test.TestHello)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "build/bdist.linux-i686/egg/mox.py", line 1374, in new_method

    raise UnexpectedMethodCallError(self, expected)
UnexpectedMethodCallError: Unexpected method call: __call__('Hello') -> None.

However, I am seeing this:

What version of the product are you using? On what operating system?
I'm using Mox 0.5.0, Nose 0.10.4, Python 2.5 and 2.6, Mac OS X 10.5.6 Intel

Please provide any additional information below.
I set up a REALLY dumb test case at http://gist.github.com/74723

This issue is actually a problem with nose.  Details can be found in 
http://code.google.com/p/python-
nose/issues/detail?id=236

The fix is in the trunk of the nose project

Please close this.  Thank you
