I managed to find Jonathan's mail:
It would break xetex on macosx (whether using xdvipdfmx or xdv2pdf),
where getFontFilename(engine) will
often return NULL.

Yes, the change is not hard, as I said earlier, but it does need to be
done with care. Probably something like
this (untested) would work:

 		engine = (XeTeXLayoutEngine)fontlayoutengine[f];
-		fontRef = getFontRef(engine);
-		if (fontRef != 0)
-			getNames(fontRef, &psName, &famName, &styName);
-		else {
-			psName = getFontFilename(engine);
+		psName = getFontFilename(engine);
+		if (psName) {
 			famName = "";
 			styName = "";
 		}
+		else {
+			getNames(getFontRef(engine), &psName, &famName, &styName);
+		}

(BTW, the xetex list would be a better forum to discuss xetex bugs and patches.)
