[STUMP] number of arguments in *destroy-window-hook*

[Luis Octavio Silva]

Dear developers,

I apologize for demanding some of your precious time. I have the
following in my .stumpwmrc file:

(defun no-windows-group-go ()
       "Gives number of windows in frame."
       (when (= (length (group-windows (current-group))) 0)
         (run-commands "gselect 1")))
(add-hook *destroy-window-hook* 'no-windows-group-go)

The function seems to work, but it produces the message:

Error: invalid number of arguments: 1

whenever a window is destroyed. What is wrong with my code?
I'm using 0.9.6 git compiled on 2009/07/17.

Thank you very much in advance for any comment.
Luis O. Silva
