Glade missing Gnome button on Palette

[Colin Law]

I don't know whether this is an Ubuntu issue or a Glade issue or very
likely just my ignorance. I am asking here first as I am subscribed
here already.

I have installed the Gtk/Gnome gui development tool Glade on Jaunty
from the repository. Glade version 2.12.2.  When I run it I expect to
see on the Palette window a button labelled Gnome in addition to two
GTK ones and one for Deprecated.  The Gnome one is missing.  I have
googled and searched bug lists to no avail.  This is my first outing
with Glade so it could easily be something simple.
