Well, it's definitely not an Anjuta problem. I just created a very similar basic program using glade3, v3.4.5 and I see the same error. After saving the project, I converted from a glade file to an xml file:

$ gtk-builder-convert glade_test.glade glade_test.xml
Wrote glade_test.xml

Here is the code I wrote (actially I copied from a glade tutorial on the web) to test this:

int
main (int argc, char *argv[])
{
        GtkBuilder              *builder;
        GtkWidget               *window;

        gtk_init (&argc, &argv);

        builder = gtk_builder_new ();
        gtk_builder_add_from_file (builder, "glade_test.xml", NULL);

        window = GTK_WIDGET (gtk_builder_get_object (builder, "window"));
        gtk_builder_connect_signals (builder, NULL);
        g_object_unref (G_OBJECT (builder));

        gtk_widget_show (window);
        gtk_main ();

        return 0;
}

When run this gives the same error:
(glade_test:7354): Gtk-CRITICAL **: gtk_widget_show: assertion `GTK_IS_WIDGET (widget)' failed

So this is probably a glade3 issue. I didn't see anything in bugzilla specifically for this but 459906 looks similar, just for other widgets.
