My crystal ball tells me you are using library zoom-frm.el (not zoom-frame.el),
and that requires library frame-cmds.el, which does use `frame-update-faces'.
But it uses that function only for Emacs releases before 21:

 (when (< emacs-major-version 21) (frame-update-faces frame))  

So you seem to be using an old copy of frame-cmds.el (and perhaps zoom-frm.el as
well?).  You can update to the latest here:
