Neat, I was looking for a good enough reason to make a 2.1.4.1 hotfix, looks like we have it :P

There is a libpng 1.6.33 now that is supposed to have this fixed.

I just compiled the master branch today and gave it a try. About 40% of my png files cannot be read, probably that issue.

Looks like it is fixed. Tested on custom 2.1.x build. Linux Mint 18.2

Yes, fixed with #12050 and may be ready for the hotfix (unless there is something important broken).
