Maybe your w3m is too old (for unicode Emacs)?

My w3m-version is "w3m/0.5.2", not too old (see below).

I've located the problem, it's the byte-compiled w3m-ems.elc.  With that
byte-compiled file in my load-path, loading w3m{.el,.elc} yields the
above error.  When I remove w3m-ems.elc from the load-path, w3m loads
without error.  My emacs-w3m was compiled against pre-unicode-2 CVS
Emacs.  Are you using the same emacs-w3m with both emacs-23.0.60 and
emacs-22.1.50?  If so, was it compiled against the former?

I use the same (compiled) files for all Emacs versions.  It was
compiled with Emacs 21: 

$ head -n6 w3m.elc 
;ELC
;;; Compiled by [...] on Tue Feb 28 20:02:10 2006
;;; from file [...]/emacs-w3m/w3m.el

;;; with all optimizations.

I'm using CVS emacs-w3m, the Changelog has this:

2007-03-23  Katsumi Yamaoka  <yamaoka@jpl.org>

	* w3m-ems.el: New file merging w3m-e21.el, w3m-e23.el and w3m-fsf.el.

I just looked at the source, and it has this:

;; We can use w3m-static- switches to make the byte code differ between
;; Emacs 2[12] and 23, if anything, it is impossible to share the byte
;; code with those versions of Emacsen.

Interesting that it works for all versions, while the byte-compiled
newer code apparently does not.

Please try rebuilding emacs-w3m using the latest Emacs CVS.

This eliminates the error and I can again read html multipart messages
with Gnus and use emacs-w3m -- in Emacs 23.0.60, but no longer in
23.0.50.  I suppose I could rebuild emacs-w3m again for the latter, but
the installed emacs-w3m will only work with one build, since it is
installed in the top level site-lisp of the Emacs installation tree:

  /usr/local/share/emacs:
  total used in directory 24 available 7888308
  drwxr-xr-x  6 root root 4096 2008-02-11 14:53 .
  drwxr-xr-x 15 root root 4096 2008-01-16 19:46 ..
  drwxr-xr-x  6 root root 4096 2007-08-24 11:29 22.1.50
  drwxr-xr-x  6 root root 4096 2008-01-16 19:46 23.0.50
  drwxr-xr-x  6 root root 4096 2008-02-11 14:54 23.0.60
  drwxr-xr-x  6 root root 4096 2007-09-18 14:56 site-lisp <== w3m

Since the numbered installation directories (i.e., 23.0.50 etc) each
have their own site-lisp subdirectory, would it be possible to install
emacs-w3m in these, and would that permit a usable emacs-w3m for each
Emacs version?

The ccl programs in w3m-ems.el, that provide the `w3m-euc-japan'
coding system and the `w3m-iso-latin-1' coding system for Emacs
21 and 22, cause this error in Emacs 23.  It is possible to
improve the source code so that it does not cause an error in
all the versions of Emacsen that emacs-w3m supports.  However,

>> Please try rebuilding emacs-w3m using the latest Emacs CVS.
>> Cf. http://article.gmane.org/gmane.emacs.w3m/7355

why I recommend rebuilding the elc files is that things causing
errors are not only them.  The typical one is the macro
`detect-coding-with-priority', of which the expanded versions
made by Emacs 22/23 are incompatible with Emacs 23/22 mutually.
There will probably be other incompatible things, though I have
not scanned all over the emacs-w3m source code yet.

In addition, I believe there will possibly be the ones other
than emacs-w3m that cause such a trouble.  So,

I think the best way is to install the PACKAGEs to

/usr/local/share/emacs/VERSION/site-lisp/PACKAGE/

for each VERSION of Emacs.  Actually I've been doing so because
I have various versions of (X)Emacsen installed.
