I also submitted an issue in 2007:

http://mail.python.org/pipermail/image-sig/2007-August/004570.html

I recently reminded Frederik, who replied:

"The NumPy support was somewhat broken and has been partially rewritten
for PIL 1.2; I'll compare those fixes with your patch when I find the
time."

So, I guess we should try the latest PIL and see if the problems are
still there?
