Did you use the same recipe I gave in my OP, aside from the space?  With
that and the space I still get the "empty" line, so as you say there
must be some other difference.  When I do emacs -Q and eval
(frame-parameters), I get this:

((parent-id . 25170646)
 (explicit-name)
 (display . ":0")
 (visibility . t)
 (icon-name)

 (window-id . "65011940")
 (top . 30)
 (left . 0)
 (buried-buffer-list)
 (buffer-list #<buffer *scratch*> #<buffer  *Minibuf-1*> #<buffer *Help*>)
 (unsplittable)
 (minibuffer . #<window 4 on  *Minibuf-0*>)
 (modeline . t)
 (width . 80)
 (height . 40)
 (name . "address@hidden")
 (environment)
 (background-mode . light)

 (window-system . x)

 (internal-border-width . 0)
 (border-width . 0)
 (font . "-*-fixed-medium-r-*--16-*-*-*-*-*-fontset-16"))

Do you have different values for relevant parameters (e.g. font)?
