Comment (by Balling):

 >Spec-compliance for non-sense..?

 I am a purist in this sense. You should always follow spec, not thinking
 about HW campatibility, and other issues. But technically this cannot
 break anything. Because the specifications says that you should skip
 unknown chunks.

 Also see #10000.

 As for Adobe Photoshop, well, it is a bug. I am telling you...

 As for GIMP the bugs there were fixed:

 Same for Image Magik.
