libglade and guile-gtk

I'm trying to find out if Guile and libglade work together, and can't seem to get the simplest sample application to run.

When I run:
	(use-modules
		(gtk gtk)
		(gtk libglade)
	)
	(define gui (glade-xml-new "gladetest.glade" "topwindow"))
	(glade-xml-signal-autoconnect gui)
	(define w (glade-xml-get-widget gui "topwindow") )
	(gtk-standalone-main w)

I get:
        GLib-CRITICAL **: file ghash.c: line 138 (g_hash_table_lookup): assertion `hash_table != NULL' failed.
        ** WARNING **: unknown widget class 'GtkWindow'

I find it hard to imagine that GtkWindow could actually be an unknown widget class. The glade file "gladetest.glade" is bare-bones:  it just has a top-level GtkWindow "topwindow", which contains a single GtkEntry.

I was surprised to find that "w" evaluates to "#<GtkLabel 809cda0>" and not to a GtkWindow. There are no GtkLabels in my glade file.

Also strange, (glade-xml-get-widget gui) without a root-level widget as an arg, dies with:
	** CRITICAL **: file glade-xml.c: line 545 (glade_xml_get_widget): assertion `name != NULL' failed.

I'm on Debian Woody, with GTK1.2, libglade0 0.17, Guile 1.4, and libguilegtk0 0.20.

I'm probably doing something very obviously wrong, but I've no idea what. 

Thanks.

Maybe you could try guile-gobject[1], which is contains a GTK+2
binding, including libglade (the glade example seems to work for me
[tm])...

Also, you might be interested in the guile-gtk mailing list[2].
