warning message in test/test_spline.py in python2_compat branch

[lucabaldini]

_delta.max() is a nan , so I wrote

#!python

import numpy
 if not numpy.isnan(_delta.max()): 
     self.assertTrue(_delta.max() < 1e-9, 'max. diff. %.9f' %_delta.max())

The test is ok, both with Python 3 and Python 2, but a warning message appears:

#!python

test_spline.py:96: RuntimeWarning: invalid value encountered in true_divide
  _delta = abs(_d(self.x2) - self.s1(self.x2)/self.y2 )

Could I say that the test works? Did I miss something?
