IOError on Scrapy Images Pipeline

I'm using Images Pipeline from Scrapy and for some images I'm getting this error:

[scrapy.pipelines.files] ERROR: File (unknown-error): Error processing file from <GET https://www.example.com/folder-name/image.jpg> referred in <None>
Traceback (most recent call last):

    raise IOError(message + " when reading image file")
IOError: broken data stream when reading image file

The images are available on the server (without redirects) and I don't find any difference between the images that work and the ones which doesn't. Any idea of what I'm missing?

Solution

This seems to be a known issue. Upgrading Pillow dependency (pip install Pillow --upgrade) fixed it.
