[Image-SIG] problems with Image.crop

what version are you using.  this bug was fixed
back in 0.3a4 (March 98).

the problem was that the _ImageCrop constructor
didn't call Image's __init__ method, which left some
attributes uninitialized.

fwiw, those line numbers don't seem to match 1.0b1
(too much work to figure out which one, though).
