I use gtkmm and libglademm daily, so maybe I can help here.  I 
experienced the same frustration when I started as well.  Here is my 
solution (workaround) to this behavior.

For each window that I design using glade-2, I make sure the Visible 
Property is set "no" for the window.  Here is a snip of code that I cut 
and paste for each class that controls a window:

class winCinque : public Gtk::Window
{
  
   public:
       winCinque();
...

   private:
       Gtk::Container *applicationspace;
       Gtk::Container *workspace;
       Gtk::Container *searchspace;
...
};

winCinque::winCinque()
{
   m_refGlade = Gnome::Glade::Xml::create(config.gladePath + 
"main/winCinque.glade");
   m_refGlade->reparent_widget("ApplicationSpace", *this);
   m_refGlade->get_widget ("ApplicationSpace", applicationspace);
   m_refGlade->get_widget ("WorkSpace", workspace);
   m_refGlade->get_widget ("SearchSpace", searchspace);
  
    //Connect signal handlers:

   // When the original glade window is reparented to this window 
object, we
   // loose the old window settings. So, we just copy the settings from 
the
   // old window to this window.
   //
   // {}TODO: Did we get all the properties that we need?
   //
   Gtk::Window *original;
   m_refGlade->get_widget ("winCinque", original);

   this->set_title        (original->property_title());
   this->set_modal        (original->property_modal());
   this->set_position     (original->property_window_position());
   this->set_size_request (original->property_default_width(),
                           original->property_default_height());
   this->set_icon         (original->property_icon());
   this->set_resizable    (original->property_resizable());
  
   // {}TODO: These are the properties that could not be set:
   //
   //    Glib::PropertyProxy<bool> property_allow_shrink();
   //      Glib::PropertyProxy<bool> property_allow_grow();
   //      Glib::PropertyProxy<bool> property_destroy_with_parent();

   show_all_children();

...

}
