[glade--] Code generation of buttons

Hello Glademm list,

I have an odd problem using glade-- to generate code... When I start a =

new project in Glade, add a new Window, then a new VBox and then a new =

Button in the VBox, the following code (part) is generated:

** part of generated window1_glade.cc: **
window1_glade::window1_glade(
)
{  window1 =3D this;
   gmm_data =3D new GlademmData(get_accel_group());
   button1 =3D Gtk::manage(new class Gtk::Button("button"));
   vbox1 =3D Gtk::manage(new class Gtk::VBox(false, 0));
   button1->set_flags(Gtk::CAN_FOCUS);
   window1->add(*vbox1);
   button1->show();
   vbox1->show();
}
** end part **

But... vbox1->pack_start(*button1) should have been somewhere. When =

compiling and running this code, the button is not visible. This is also =

the case when placing buttons in the other containers. However, when I =

add the button directly to the Window, the Button does get added:

** part of generated window1_glade.cc: **
window1_glade::window1_glade(
)
{  window1 =3D this;
   gmm_data =3D new GlademmData(get_accel_group());
   button1 =3D Gtk::manage(new class Gtk::Button("button"));
   button1->set_flags(Gtk::CAN_FOCUS);
   window1->add(*button1); // <---
   button1->show();
}
** end part **

Other components do get added to the VBox, such as labels. When I for =

example add a label and a button to the VBox, the following code is =

generated:

** part of generated window1_glade.cc: **
window1_glade::window1_glade(
)
{  window1 =3D this;
   gmm_data =3D new GlademmData(get_accel_group());
   label1 =3D Gtk::manage(new class Gtk::Label("label"));
   button1 =3D Gtk::manage(new class Gtk::Button("button"));
   vbox1 =3D Gtk::manage(new class Gtk::VBox(false, 0));
   button1->set_flags(Gtk::CAN_FOCUS);
   vbox1->pack_start(*label1); // <--
   window1->add(*vbox1);
   label1->show();
   button1->show();
   vbox1->show();
}
** end part **

So... Am I overlooking something terrible, or is this a bug?

Version info:
