And it solves it for me as well. So I suggest the problem might partly
be in the documentation for Gtk2::GladeXML -- it says

   This extension module binds libglade to Perl so you can create and
   manipulate user interfaces in Perl code in conjunction with Gtk2 and
   even Gnome2

-- but it does not mention that the SYNOPSIS example needs expanding
for a Gnome project.

Updates to later versions of the Debian packages, amongst others from
Gnome 2.4 or 2.6 to 2.8.
