bug#17589: 24.3.91; lisp/frameset.el

[eg5cue@gmail.com]

cmdline: emacs -Q
version: git 24.3.91.1 (branch emacs-24)

frame 'a': (C-x r f a)
changing buffers and windows ...
frame 'b': (C-x r f b)
when i want to go back to 'a' (C-x r j a) emacs can't remember the frame and
open random buffer instead. (no error)
i tried both GUI and terminal versions.
