Sorry for the late reply, I haven't had time to look at this problem

This line is wrong, WebKitDOMDocument is not a WebKitDOMElement, you
should use webkit_dom_document_get_elements_by_tag_name() instead. What
WebKitGTK+ version are you using? because recent versions will give a
runtime error when passing the wrong DOM object to a method.

I have a added this as a test case to WebKit2 DOM bindings tests, see

No idea, maybe it was because you were using the wrong method.
