Is this with emacs -Q and your original scenario, i.e., just the

(add-hook 'delete-frame-functions
          (lambda (frame)
            (dolist (elem (window-list frame))
              (kill-buffer (window-buffer elem)))))

addition?  If you simplify that to removing the ‘window-list’ call and
only kill the *Colors* buffer does the crash occur as well?
