Hello,

emacs -Q:

(progn (readablep (current-window-configuration))
       (current-buffer))
==> #<buffer  prin1>

After evaluating such a `readablep' call, weird things can happen
because of this buffer being current.  I tried to actually display that
buffer and the window I got looked quite funny, one second later Emacs
had crashed.

TIA,

Michael.
