Hi folks,

I'm wondering if the following rings any bells for you... Right now,
on an ubuntu 13.04 machine, if I install mpl master (say to my home
directory), the IPython test suite fails here:

iptest -vx IPython.core.tests.test_run

...

======================================================================
ERROR: Test that namespace cleanup is not too aggressive GH-238
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/nose/case.py", line 197, in runTest
    self.test(*self.arg)
  File "/usr/lib/python2.7/dist-packages/numpy/testing/decorators.py",
line 213, in knownfailer
    raise KnownFailureTest(msg)
KnownFailureTest: This test is known to fail


If I uninstall mpl from master and revert to the system version
(1.2.1), then it's all OK.  We'd seen this problem a few years ago,
but in that case it was the opposite: mpl master was OK and the issue
was mis-packaging by Ubuntu:

https://github.com/ipython/ipython/issues/823
https://bugs.launchpad.net/ubuntu/+source/matplotlib/+bug/871176

But now the problem appears to be caused by mpl master.  Can you think
of any recent changes to mpl in how you load your nose plugins that
could be causing this?

Since SciPy'13 is coming and I know Mike will be there, I'm happy to
try to debug this face to face in Austin.  I just wanted to put it on
your radar, in case it's an easy fix (esp. if it's one you can apply
before 1.3.0 goes out).

Cheers,

f
