"cl-map-keymap: Lisp nesting exceeds max-lisp-eval-depth"

[emacs user]

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

During the past few weeks, I have been getting an error message from
the latest version of the cvs gnu emacs:

"cl-map-keymap: Lisp nesting exceeds max-lisp-eval-depth"

which then makes emacs unusable.  I
managed to track the problem to the x-symbol package.  to reproduce,
install x-symbol and:

/usr/local/emacs/src/emacs -q --no-site-file -l ~/.emacs.debug&

where the .emacs.debug file is:
-------------------------------
(setq load-path (append (list (expand-file-name "~/.emacs.d"))
load-path))
(defvar x-symbol-lisp-directory "~/.emacs.d/x-symbol/lisp/x-symbol")
(setq load-path (cons x-symbol-lisp-directory load-path))
(setq x-symbol-data-directory "~/.emacs.d/x-symbol/etc/x-symbol")
(load  "~/.emacs.d/x-symbol/lisp/x-symbol/auto-autoloads")
(x-symbol-initialize)
(eshell)
-------------------------

and the resulting *Messages* buffer is attached.  turning on debugging
on error, or using --debug-init switch does not result in any traceback
information, unfortunately...

here is the Messages buffer with the error message at the bottom
