        * Khtml/khtml_part.cpp:
        (KHTMLPart::checkCompleted): If the document is NULL, assume this frame has
	not started loading yet so it could not possibly be finishing here...
        (KHTMLPart::stop): ...unless the part is explicitly stopped and there is still
	no document, in this case we must have hit an error or been loading a non-HTML
	frame.
        * khtml/khtml_part.h:
