The green turtle graphic on the page should have two eyes at the top end of the ellipse. Each eye is a filled circle clipped to the ellipse.
On 3.0.4 (eg on OS X 10.4.11) the eyes get drawn but not clipped, because of a 'use' element in the clipPath, see bug 15514.
On nightly r28924 the eyes are gone completely.
This works on Firefox.
I'm entertained that http://www.amberfrog.com/logo/ looked fine in FFb1 and is now totally borked in FFb2.
I think we already have a bug about WebKit's behavior on this page.
Now that bug 15514 is fixed, I believe this can be closed. Please confirm.

Original reporter (me) confirms fixed in r28997.
