If you need your app to work under older versions of GTK+/GNOME you
should use the appropriate version of Glade. From the README:

Compatable Versions:

  Glade 2.12.x - GNOME 2.12.x                   (GTK+ 2.8.x)
  Glade 2.10.x - GNOME 2.10.x                   (GTK+ 2.6.x)
  Glade 2.6.x  - GNOME 2.6.x/2.8.x              (GTK+ 2.4.x)
  Glade 2.0.x  - GNOME 2.0.x/2.2.x/2.4.x        (GTK+ 2.0.x/2.2.x)

Apps developed with one version of Glade/GTK+/GNOME should work on all
later versions.

Making apps work on previous versions of GTK+/GNOME would need a lot of
work tracking which properties are available in which versions. You
might want to add the feature request to the glade-3 product in
bugzilla, though I'm not sure if they'll do it.
