I am copying this to John and Charlie so they will know that all known
imshow-related problems have been resolved (correct?). (Also to the
devel list, just in case.) This and the previous message were not copied
to either of the lists.
What is the difference between numpy.ma and the other masked array
implementations that caused the exception? Is this something that
should be fixed in numpy.ma?
