`window-state-put' as used within the following functions does not work.
Please see *Backtrace* below for error.  (See also post to
help-gnu-emacs <at> gnu.org with subject "Save and load window states")

Steps to reproduce: 
1) Start via `emacs -Q'.
2) evaluate the two functions:
(defun my-save-frame ()
  (interactive)
  (let ((buf (find-file-noselect "/tmp/emacs-layout")))
    (set-buffer buf)
    (erase-buffer)
    (print (window-state-get) buf)
    (save-buffer)
    (kill-buffer)))

(defun my-load-frame ()
  (interactive)
  (let ((buf (find-file-noselect "/tmp/emacs-layout")))
    (set-buffer buf)
    (beginning-of-buffer)
    (window-state-put (read buf))
    (kill-buffer)))

3) Do a `M-x my-save-frame' and after that `M-x my-load-frame'

Debugger entered--Lisp error: (invalid-read-syntax "#")
  read(#<buffer emacs-layout>)
  (window-state-put (read buf))
  (let ((buf (find-file-noselect "/tmp/emacs-layout"))) (set-buffer buf) (beginning-of-buffer) (window-state-put (read buf)) (save-buffer) (kill-buffer))
  my-load-frame()
  call-interactively(my-load-frame t nil)
  execute-extended-command(nil)
  call-interactively(execute-extended-command nil nil)
