simple loop animation gifs like the bugzilla dinosaur head are flashing between one frame and transparent.

It appears to be showing just one frame (probably the first) and one transparent frame alternately. The animations have many frames.


Reproducible: Always

Steps to Reproduce:
1. http://www.solaire-chauffe-eau.info/flag_fr.gif
2. note blinking animation not smooth animation.

Actual Results:  
correct gif animation sequence

Expected Results:  
alternately first frame and transparent frame. Rest on animation not shown.

I found that a cairo update was at the root of this, reverting to x11-libs/cairo-1.8.10 fixed the problem.

Since a similar issue also showed defects in svg rendering I'll mark this as a dupe.
