Please write a bug report so Emacs developers will take care of this.

Meanwhile you can try to add an entry like

  '(warning-suppress-types (quote ((undo discard-info)))))

to your customizations which usually reside in your .emacs (or _emacs)
file.  That is, if so far you have customized `debug-on-error' and
`yank-excluded-properties' only, your .emacs should then contain the
following form:

(custom-set-variables
   ;; custom-set-variables was added by Custom.
   ;; If you edit it by hand, you could mess it up, so be careful.
   ;; Your init file should contain only one such instance.
   ;; If there is more than one, they won't work right.
  '(debug-on-error t)
  '(warning-suppress-types (quote ((undo discard-info))))
  '(yank-excluded-properties t))

Restart Emacs and tell us whether it works.

Thanks, martin.
