This looks like <http://projects.scipy.org/numpy/ticket/1936>

The ValueError is raised in "numpy\lib\npyio.py", line 804, in loadtxt.

Npyio.py is identical for numpy 1.6.0 and 1.6.1.

This is an actual function call from line 804, which works in numpy 
1.6.0 but fails with 1.6.1:

>>> np.array([(0, ((0., 0., 0.),))], dtype=[('et', '<i4'), ('r', '<f8', (3,))])
