Repro-file package

Tested on:

OS: Ubuntu 12.04

librsvg: ASAN build version 2.36.1

The attached repro-file causes rsvg-convert, rsvg-view-3 and nautilus (svg preview enabled), to hang indefinitely.
Comment 1 Federico Mena Quintero 2015-02-06 17:53:29 UTC 
The SVG has these:

        <linearGradient id="cycle2" xlink:href="#cycle1">
            <stop offset="0" stop-color="red" />
            <stop offset="1" stop-color="orange" />
        </linearGradient>

        <linearGradient id="cycle1" xlink:href="#cycle2"/>

And the functions that resolve a chain of gradient properties end up in an infinite loop, since the gradients reference each other.  I'll fix this.
