[Image-SIG] Image.split broken when image file isn't loaded

[Chris Lamb]

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,
