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?
