ispell-french does not function on GNU Emacs 22.1.1

["NAGATA Yoshihisa" <ynagata@fukuoka-u.ac.jp>]

How to reproduce the bug:

0. Please prepare any text file written in French.
(iso-8859-1 or utf-8)
1. Open the file with Emacs.
2. Choose "Select Francais Dict" from the menu-bar.
3. Do "Spell-Check Buffer"
4. Then, you will have the error message below in
the mini-buffer:
Invalid regexp: "Range striding over charsets"

I thank you in advance for your help.

P.S.
1. This bug does not appear with command-line ispell.
2. Ispell-french worked with the GNU Emacs 21.3.1. (on openSUSE 10.2)
