-2 is not bizarre.  It's purpose is to give the calculator window 2
lines.

The binding of `window-min-height' is here to avoid that `split-window'
complains about too small windows.

All this shouldn't bother us since we already know that we get the
standard value -2 here.

Hence we seem to be left with the fact that your configuration has

(let ((split-window-keep-point nil)
      (window-min-height 2))
  (split-window-vertically -2))

fail for some reason.  Could you please verify by evaluating that form?
