OK, I discovered a rather easy demonstration of what looks to be a 
(possibly the same) bug (adding 'ylim' to the image_origin demo):

from matplotlib.matlab import *

x = arange(100.0); x.shape = 10,10


subplot(211)
title('blue should be up')
imshow(x, origin='upper', interpolation='nearest')
set(gca(),'ylim',(0,23))

subplot(212)
title('blue should be down')
imshow(x, origin='lower', interpolation='nearest')
set(gca(),'ylim',(0,23))

#savefig('image_origin2')
show()
