Compare http://commons.wikimedia.org/wiki/Image:London_Underground_Zone_1.svg with http://commons.wikimedia.org/wiki/Image:London_Underground_Zone_1.png and you will see that the former has rednered with large white gaps at the top and bottom.
Renders correctly with librsvg 2.14.0; upgrade will fix this.
Thumbs now render correctly; old renderings should be cleared out within a couple days.
