Is there a way to invert gtk_ui_manager_get_path()

[Richard Shann <richard shann virgin net>]

The function gtk_ui_manager_get_path() gets the xml path to a widget in
your menu hierarchy. Is there a way, given a widget to find this path?
Note this is not the path gotten from gtk_widget_path() which is the
container hierarchy. I want the menu hierarchy (so as to be able to
insert menu items there in some future invocation of the program).
