Safari 2 Crashes on $A(node.childNodes)

[subtleGradient]

This crashes Safari 2 on Leopeard every time.
(note that if you relaunch safari2 after it crashes it will relaunch with the safari3 rendering engine)

Seems to be an issue with passing .childNodes into $A() on an element that isn't attached to anything.

var node = new Element('div', {html: $('test').innerHTML});
$A(node.childNodes);

I can't look at it anymore right now.
I originally found the issue when I was using the Request.HTML code and it's taken me a while to boil it down to this issue.
When I get some more time I can try and boil it down some more.

Accessing node.childNodes.$family or any other undefined property of childNodes causes Safari 2 to crash in some cases.
Requirements for a crash seem to be: The node is not in the DOM and probably only text is set as node.innerHTML, if innerHTML is '<p>test</p>' for example it seems not to crash.

function init() {
        var node = document.createElement('div');
        node.innerHTML = 'doh';
        node.childNodes.$family; // or any undefined value
}
