Not really familiar either, but i had solved it this way:
http://git.xfce.org/users/landry/gigolo/commit/?id=dd0e669bfd2df91ccad081f4a3c4fdf1a6b70a38
For me only the treeview was 'shrunk', not the icon view.

Since then i converted some stuff from deprecated to non-deprecated APIs,
and still on the line there's:

- GtkImageMenuItem -> ?
- GtkAction -> GAction ?
- GtkStatusIcon -> ?
- GtkUIManager -> no replacement ?
- Still some GtkStock warnings

But feature-wise, it should still work. More testing is always welcome
of course...
