OK.  The reason may be twofold: `save-selected-window' may twice
select a window with norecord nil:

		(set-frame-selected-window (car elt) (cdr elt)))) ; <--- here
	 (if (window-live-p save-selected-window-window)
	     (select-window save-selected-window-window)))))) <--- and here

Fixing these two fixes the bug.  I have to find out how to do this in an
unobtrusive way though.

martin, who'd never ever run `window-configuration-change-hook'
buffer-locally in the first place ;-)
