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:

In GNU Emacs 25.0.50.55 (x86_64-unknown-linux-gnu, GTK+ Version 3.18.6, cairo
