------- Additional Comments from Daniel Bates <dbates at webkit.org>
This change does not cause any DRT regressions on my Mac.

As far as I can tell from looking at the callers of Frame::setDocument() and
the Document creation process, it doesn't make sense for Frame::setDocument()
to be passed a non-null PassRefPtr<Document> whose Document has a null frame
(i.e. Document::frame() == 0).
