Hi, Image.split appears to be broken when the image file isn't loaded first.
My testcase is:
>>> from PIL import Image
>>> x = Image.open('test.png')
>>> x.split()
[..]
AttributeError: 'NoneType' object has no attribute 'bands'
I think Image.point was broken in the same way recently; the client
workaround of calling Image.load works here too.
Patch attached.
Regards,
