Feeding a numpy array to make_surface gives an error:

to reproduce:
$ python
>>> import numpy
>>> import pygame
>>> a = numpy.zeros((10,20,3), numpy.uint8)
>>> pygame.SurfaceArray.make_surface(a)

output:
    IndexError: bytes to write exceed buffer size
expected:
    <Surface(10x20x32) SW)>

Stepping through inside, it seems that the buffer has the right size, and the data is the right length at the point the buffer write occurs. But the buffer write fails (and I can't step that)

I'm 99% certain that this worked before I upgraded from Kubuntu 13.10 to 14.04
