No, I don't build the entire interface at one point.  In the first
section, I build an interface that uses the first toplevel.  Later, I
may (or may not) build an interface that uses the second top level.

Unfortunately, I cannot use the gtk_builder_add_objects_from_file()
method since I need to be compatible with version 2.12.  IIRC that
method was added later on.

Note that I am converting this work from a libglade interface to a
gtk.builder interface.  libglade seems to handle the
multiple-top-levels-in-one-glade-file thing a little easier, though
that could just be my lack of understanding,
