Quick comment on the scrolling: When you close the list, and click the
attribute again, the list will have a scrolling arrow at the bottom, and
that works. I think Benny mentioned that earlier on this list as being a
GTK thing.

Yes, a GTK bug. Somebody should try on 3.8, and if present, post a bug ticket on the gnome tracker
