What you're doing is just very strange - you shouldn't need to
set_usize() on the scrollbars. So this probably confuses GTK pretty
badly. I can't imagine why you set_usize() on the scrollbars?

I would do this as a simple GtkTable, or else use GtkScrolledWindow. 
In the GtkTable of course you need a 2x2 table where the drawing area
is attached in cell 0, 0 and the horizontal bar is on the bottom in
cell 0, 1 and the vertical bar on the left in 1, 0. If you set the
table packing right there should be no need to set_usize().

(In general, set_usize() should be rarely used...)
