Note that the name of a buffer may change in the period lasting from
when you saved the window configuration until the buffer gets killed.
Any such change is handled by 'kill-buffer' but cannot be easily traced
when you save the name together with a window configuration.  You could
try 'buffer-list-update-hook' but that might be overkill.  And if you
saved that name in a permanent window parameter, you are lost anyway
because you cannot access the parameter in the saved configuration.

A similar thing may happen to dired-filename and revert-buffer-function
but there are hardly any suitable means to reasonably trace changes to
what these stand for in the first place.
