Does the value set match the page size in the underlying
GtkAdjustment? (gtk_range_get_adjustment())

If you connect a handler that prints a message to the "value-changed"
signal of either the GtkRange or the GtkAdjustment, this should tell
you if it's adjusted twice.

It's just a gdouble in the adjustment; no units.
