OK so that might as well mean that I can uninstall libglade
completely from my Ubuntu 9.04 Linux system.

Too bad this could not have been fixed in the code.
 What are the reasons for it not working out of the box?
Are there some widget property incompatibilities?

OK so it looks like I will be uninstalling libgnomeui as well.
I never liked the idea of gnome-specific widgets which cannot
then be ported to other platforms anyway.

You can at least start by loading the file in Glade, fixing

Looks like I am going to have to learn how to use GtkBuilder
to port my C code which worked with glade 2 code to C code
that works with glade 3.

Well, when I try to open the file http://whm.sf.net/foo.glade
with glade-2 I am successful but with glade-3 I get a
segmentation fault:

GladeUI-Message: No displayable values for property GtkScaleButton::size

Obviously something needs to be done for me to be able to open the
file with glade-3, but I am not sure exactly what. Any ideas?

APART FROM THIS...

By the way, is the book "The Official Gnome 2 Developer's Guide"
as in the links appearing below now an outdated book?

http://www.amazon.com/gp/search?index=books&linkCode=qs&keywords=1593270305
http://developer.novell.com/wiki/index.php/The_Official_Gnome_2_Developer%27s_Guide

Is there better more up-to-date books on Gtk/Glib/Glade deve lopment
which are more relevant nowadays (given that as you mentioned the
development libraries are now more gnome-independent?)

Looks like nowadays the reference books on this subject are:

- Foundations of GTK+ Development (Expert's Voice in Open Source)
(Paperback)
  by Andrew Krause

and

-  Gtk+ Programming in C (Paperback)
  by Syd Logan

but I am not sure about whether any of these cover GtkBuilder and glade.

Any suggestions or recommendations on selecting a proper place
to work with are very welcome (I have used Gtk and Glib in the past
but now I am somewhat rusty on it and need something to go by in
order to upgrade properly),

Thank you for your help and feedback,
