This means something's wrong with your `split-window'.  C-x C-e gets me
for

(let ((window-min-height 2))
   (split-window-vertically -3))

=> Make a two lines window at bottom

(split-window-vertically -3)

=> Lisp error: (error "Window height 3 too small (after splitting)")

(let ((window-min-height 2))
   (split-window-vertically -2))

=> Make a one line window at bottom

(split-window-vertically -2)

=> Lisp error: (error "Window height 2 too small (after splitting)")

which is the expected behavior.  Your behavior is wrong because

(let ((window-min-height 2))
   (split-window-vertically -2))

should not_raise an error while

(split-window-vertically -3)

should.  My build is Emacs 22.1 with a few modifications.  Maybe
something changed since then.

Can you run `split_window' with GDB and find out why it fails?
