--- Comment #3 from John Friend <jfrie at protonmail.com> ---
I chased the same bug down and arrived here to report it.
The fix simply requires running imagemagick on the filed as described
in the SO question: "mogrify foo.png".

You can verify the fix by grepping the (binary) file for the chunk tag
"iCCP". After repairing the files grep should report a non-match.

I would submit a patch, but the tree snapshot is 1.8GB compressed (!) and that's too much to ask.

Since the files have been there for 7 years, and libpng1.6 has been yelling for 5, this may seem like a minor nuisance. But my system's log files are littered with these messages, so it *would* be great to fix this.

You are receiving this mail because:
You are the assignee for the bug.
