Bug#990204: Failing autopkgtest with pillow 8.1.2+dfsg-0.2/ pillow 8.2

[Moritz Muehlenhoff]

Source: skimage
Severity: serious

pillow 8.1.2+dfsg-0.2 backported a few security fixes from pillow 8.2.

One of the changes breaks the autopkgtest/testsuite of skimage:
https://ci.debian.net/data/autopkgtest/testing/amd64/s/skimage/13102974/log.gz

I dug around in skimage git and this appears to be fixed already in
https://github.com/scikit-image/scikit-image/commit/4be0f1b0a578e5239f2352af1aec2c80011ed4da
so it would be great if you could cherrypick this patch for unstable.

Cheers,
