+Subject: [PATCH] Drop the PangoFont find_shaper virtual method
+
+This API has been removed from Pango 1.44.6, because it was completely
+unused by anything.
+
+However, PyGTK tries to bind everything, even unused API.
+
+Removing this from PyGTK means we can build it against the latest Pango
+again.
