What did you do?
Following on from #4509 after the 7.1.0 release, we have a new issue that cropped up opening a png from scikit-image.
What did you expect to happen?
Not error.
What actually happened?
It errored.
What are your OS, Python and Pillow versions?
- OS: Linux
- Python: 3.8.2
- Pillow: 7.1.0
The code should just be loading a scikit-image PNG data:
from skimage import data
original = data.camera().astype('float')The error message is:

AttributeError: 'NoneType' object has no attribute 'read'Since this is scikit image loading one of their PNGs, I wonder if it's actually a bug there.
