David Levin pointed out that the change to WebViewImpl in http://trac.webkit.org/changeset/69633 incorrectly used PassRefPtr for a local variable instead of RefPtr. I thought I had seen an assertion failure in this code change in http://trac.webkit.org/changeset/69624 but after reverting it it seems not.
