I have still been unable to reproduce the csgraph.shortest_path failure.

I can reproduce this for about 1 in 10 runs, which is really weird because
I can't find any randomness in the test or code. Plus, it once again shows
how annoying generator tests are; can't see which method is failing.
Failures are also not always the same:

<failure 1>
x and y nan location mismatch:
 x: array([[  0.,  nan,   3.,   2.,   4.],
       [ nan,  nan,  nan,  nan,  nan],
       [  1.,  nan,   0.,   3.,   5.],
       [  1.,  nan,   4.,   0.,   3.]])
 y: array([[ 0.,  3.,  3.,  1.,  2.],
       [ 3.,  0.,  6.,  2.,  4.],
       [ 3.,  6.,  0.,  4.,  5.],
       [ 1.,  2.,  4.,  0.,  2.]])


<failure 2>
(mismatch 30.0%)
 x: array([[ 0.,  3.,  3.,  2.,  4.],
       [ 3.,  0.,  6.,  2.,  4.],
       [ 3.,  6.,  0.,  5.,  7.],
       [ 1.,  1.,  4.,  0.,  3.]])
 y: array([[ 0.,  3.,  3.,  1.,  2.],
       [ 3.,  0.,  6.,  2.,  4.],
       [ 3.,  6.,  0.,  4.,  5.],
       [ 1.,  2.,  4.,  0.,  2.]])


Any idea where to look?
