In the GTK+ FAQ we read:

    4.12 Why doesn't my widget (e.g. progressbar) update?

    You are probably doing all the changes within a function without
    returning control to gtk_main. Most drawing updates are only placed
    on a queue, which is processed within gtk_main. You can force the
    drawing queue to be processed using something like:

	while (gtk_events_pending())
		gtk_main_iteration();

    inside you're function that changes the widget.

Maybe this proves helpful in your case, too.  Dunno, since I haven't
tested this, but it looks like it would do the job.
