Have the mechanism of font selection been changed in Emacs 22?

[zrr]

Hi all,
   I updated the emacs-unicode-2 branch yesterday. But it seems that
   the current emacs 22 can't correctly select the chinese fonts in
   the way which I specified 3 month ago.

   My setting is as follows:

      (create-fontset-from-fontset-spec
          "-etl-fixed-medium-r-*-*-16-*-*-*-*-*-fontset-most,
han:-misc-simsun-medium-r-*--16-*-*-*-*-*-gbk-0" t)

   But when I start Emacs in X, it complains:

       Debugger entered--Lisp error: (wrong-type-argument sequencep fontset)
  new-fontset("-etl-fixed-medium-r-*-*-16-*-*-*-*-*-fontset-most" ((han 
["misc-simsun" "medium" "r" nil "" "gbk-0"])))
  
create-fontset-from-fontset-spec("-etl-fixed-medium-r-*-*-16-*-*-*-*-*-fontset-most,\nhan:-misc-simsun-medium-r-*--16-*-*-*-*-*-gbk-0"
 t)

  The same setting works perfectly in the Emacs 22 dated 2004-10-22.

  Is there any internal change of the font selection method?

  Any suggestion would be appreciated.

Regards!
