RecentInfo should have reference() and unreference() functions that are
implemented with
gtk_recent_info_ref() and gtk_recent_info_unref()
http://developer.gnome.org/doc/API/2.0/gtk/gtk-GtkRecentManager.html#id3947230
because they are mentioned in the _CLASS_BOXEDTYPE macro:
http://cvs.gnome.org/viewcvs/gtkmm/gtk/src/recentinfo.hg?view=markup

If they aren't being generated then that's a bug. Sorry, I'm not at my
computer now.

Yes, you probably need to provide a Traits specialization. You should be
able to find some similar onese around gtkmm and friends.
