Have yor read the FAQ too?

    http://www.gtk.org/faq/#AEN602

Also, are you aware gtk_progress_bar_update() is deprecated?

gtk_progress_bar_set_fraction() -- which is the function to
use -- only queues the drawing.  The drawing then actually
occurs in Gtk+ main loop, which does not have a chance to
run without gtk_main_iteration().
