>Description:
Some animated gifs in latest firefox with cairo 1.10.0+ only display a single frame, making them blink instead of animate.
>How-To-Repeat:


1. Install www/firefox (firefox-3.6.12,1) with graphics/cairo (cairo-1.10.0_3,1)
2. Open a gif such as http://fans.avalanche.nhl.com/community/public/style_emoticons/default/whistling.gif in firefox.

Result will be a blinking image.
>Fix:
Downgrade graphics/cairo to 1.8.10. I had a backup package of cairo-1.8.10_1,1 which gets rid of the problem.
