Re: bug in PIL 1.1.7 Image.split()

Good catch. The breakage is caused by a 1.1.7 fix that treats
single-band images as a special case; unfortunately, the fix checks
that attribute before actually loading the image...  I'll provide a
patch later, but you can of course work around it by adding an
explicit load to your code.

Thanks /F
