Full log
Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
To reproduce the problem, configure Emacs --with-cairo, and then run these shell
commands:
wget https://upload.wikimedia.org/wikipedia/commons/f/f5/All_palaeotemps.png
emacs -Q All_palaeotemps.png
Emacs shows a blank (or sometimes garbled) screen instead of the image.
I think the problem is that lookup_rgb_color is returning garbage.
Here are more details about the configuration, built on Fedora 23 x86-64:
