Incorrect rendering of SVG files

Hello!

As long as the support of SVG on GTK is marked as
complete I think the result I'm seeing is a bug.

Consider the following SVG file:

<?xml version="1.0" encoding="UTF-8"?>
<svg xmlns="http://www.w3.org/2000/svg" width="32" height="32">
<rect style="fill:red" y="0" x="0" height="32" width="32" />
</svg>

The image above is rendered as two rectangles side-by-side.
On red and another one blue while it appears all red in any other
image viewer, image editor or web browser.

See the screenshot at: http://ogg.ge/netsurf.png

I'm using NetSurf 3.4 on Debian Jessie GNU/Linux.
I will happily share any other technical details if needed.

Thanks.
