 scipy.ndimage.measurements.center_of_mass
 does not work with a masked_array (numpy.ma)

 I think one of two things should happen: either the mask is honoured and
 the center_of_mask is only calculated on elements without a mask, or the
 function should return an error to indicate that the operation will not
 work as expected.

 Just returning some value seems therefore to be a bug.
