There are a couple surprising things, one is mentioned here:
http://developer.gimp.org/api/2.0/gtk/GtkTextView.html#gtk-text-view-
get-iter-location

buffer coords vs. various other coordinate origins you might be
expecting.

Another is that the text view gets laid out asynchronously, so the
coords of a given iter will change as this happens. Right after you
insert a line it's normally 0-height for example.

Could also be a bug, especially since you're using 2.0 which was the
first appearance of TextView and is pretty old by now.
