Weird cubist output in IE

[dflock]

Hi,
I've been playing around with Raphael the last couple of days and
ended up with this prototype:

http://gator.codeistry.com/uniform_builder_prototype/cow.php

This uses Raphael to render the SVG cow, and jQuery to do the colour
changes on clicking on the HTML form stuff on the right. This works
perfectly in everything but IE - which renders the cow in a really
weird half-inside out cubist style. You can see what the original SVG
cow's supposed to look like by clicking the link at the bottom.

I'm maybe guessing that this is something to do with open/closed
paths, or rounding or something?

Has anyone got any idea why this happens or what to do about it?

Thanks,
Dunc
