Repro - WebCore::ContainerNode::childNodeCount ReadAV at NULL (73c50888d671e6db8bd5929edc78bd92)

Attached is a repro for a NULL pointer crash in WebCore::ContainerNode::childNodeCount. I'll add a few more related crashes. It appears this bug can only be used to crash WebKit by causing a NULL pointer exception.
