What did you do?

Pickle TIff image with pillow==11.1.0 and then de-serialize it with pillow==11.2.1

What did you expect to happen?

I expect the image to be successfully de-serialized

What actually happened?

It's crashing with

What are your OS, Python and Pillow versions?

• OS:
  Mac OS, Ubuntu
• Python:
  Python 3.12.7
• Pillow:
  11.2.1

To reproduce the issue
Install pillow==11.1.0 and execute the following code (you can download the tiff from - https://people.math.sc.edu/Burkardt/data/tif/at3_1m4_01.tif)

from PIL import Image import pickle image = Image.open('./at3_1m4_01.tif') pickle.dump(image, open('./test.pickle', 'wb'))

Then install pillow==11.2.1 and de-serialize the file

 pickle.load(open('./test.pickle', 'rb'))

It's crashing with

File ~/.pyenv/versions/3.12.7/envs/forms/lib/python3.12/site-packages/PIL/ImageFile.py:260, in ImageFile.__setstate__(self, state) 258 def __setstate__(self, state: list[Any]) -> None: 259 self.tile = [] --> 260 self.filename = state[5] 261 super().__setstate__(state) 

I tested with regular PNG file and the issue is not reproducible.
