If you view the page, click the down arrow next to Home and then click its up arrow, Safari crashes. This may be because it's trying to call insertBefore(node, node) ? I'm not for sure.

The problem turns out to be that if Parent has children A and B (A being B's previous sibling), then Parent.replaceChild(A,B) messes up the DOM tree.
