Hello,
as reported in http://bugs.debian.org/854280, lib/matplotlib/mpl-data/sample_data/necked_tensile_specimen.png calibration code is copyrighted by Apple but no license is specified, so the "all rights reserved" means it's a non-free package, possible even totally non-distributable (ie it shouldnt be in the upstream tarball/repo at all):

what would be the impact (in this case for Debian, in the immediate) if we just remove that file from what we distribute in debian? something will break? how badly it would break?

thanks for considering!

    attn @breedlun

    Came in via #2995 I have a suspicion that the meta-data is just wrong.

    Hmmm... @tacaswell could be right that the meta-data is wrong. I created that png file using paraview which is an open source visualization package, but I dunno if that means the color profile was necessarily open source.

    There is nothing special about that image, though. We could replace it with just about any high rez image and still get the same point across.

    please note that this is an important bug for debian (it's what we call a Release Critical bug, which is possibly held back the release of the new debian stable distribution), i am open to any resolution of this, and i'm willing to help/test as needed

    You can just leave it out; it's only used in examples/images_contours_and_fields/interpolation_none_vs_nearest.py (which is currently deleted on master, although the description may return somewhere.)

    thanks @QuLogic i will remove it from the tarball (and binary packages) distributed by debian, it'd be great to remove it entirely from matplotlib future releases (either 2.0.x and future 2.x) -- thanks!

    sadly it was not "just remove it" as it generated:

    You need to remove the example that uses it as well.
