After minimising my init.el and macroexpanding to get rid of 
use-package, I now have a minimal recipe to reproduce the problem.
Run:
    emacs -Q --load bug43700.el

--[bug43700.el]-------------------------------------------------
(custom-set-faces
 '(default
    ((((class color)) :font "DejaVu Sans Mono-9"))))

(custom-set-faces
 '(fixed-pitch
   ((((class color)) :font "DejaVu Sans Mono-9"))))

(custom-set-faces
 '(variable-pitch
   ((((class color)) :font "Liberation Sans-11"))))

(require 'org)
(eval-after-load 'org
  '(define-key org-mode-map [remap org-archive-subtree] #'ignore))

(find-file "~/foo.org") ; Create org buffer (file need not exist)
(make-frame)
--[end bug43700.el]---------------------------------------------

My Windows 10 system has:
 - version 2.37   of Deja Vu Sans Mono
 - version 2.00.1 of Liberation Mono

Hopefully you can reproduce this issue.
