widget-mouse-face problem

[Jose A. Ortega Ruiz]

Hi,

i'm using a very recent emacs 23 compiled from CVS. i usually run it
from a screen session and use emacsclient -t in a urxvt, and,
occasionally, emacsclient -c to run an X instance. after i do the
latter, trying to enter any buffer containing widgets (e.g. a
customization buffer or an emacs-w3m page) fails with the following
error:

Debugger entered--Lisp error: (error "Symbol widget-mouse-face may not be buffer-local")
  make-local-variable(widget-mouse-face)
  Custom-mode()
  custom-buffer-create-internal(((widget-mouse-face custom-variable)) nil)
  custom-buffer-create(((widget-mouse-face custom-variable)) "*Customize Option: Widget Mouse Face*")
  customize-variable(widget-mouse-face)
  call-interactively(customize-variable t nil)
  execute-extended-command(nil)
  call-interactively(execute-extended-command nil nil)

(this is when i try to customize widget-mouse-face itself; similar
errors occur in the other cases). if i ask for the value of
widget-mouse-face, it's usually set to 'highlight.

Does this ring any bell?

Thanks!

I can't reproduce this on latest CVS, i686-pc-linux-gnu, GTK+ Version
2.12.9.  What's your setup?  Please send a precise recipe for
reproducing this bug, beginning with emacs -Q.

Variable can't be made both buffer local (make-local-variable) and frame
local (make-variable-frame-local). Do you use color-theme?

Yes, that seems to be the problem. In my theme file, widget-mouse-face
was set to 'highlight, with a form (widget-mouse-face . highlight) near
the beginning. Removing this assignment seems to fix my problem: is this
the right fix?

Thanks!

Frame local variables are deprecated and Emacs 23 signals an error when
trying to make a frame local variable buffer local (or vice versa), so
color-theme should avoid make-variable-frame-local. Also see
color-theme-is-global.

(I don't use color-theme.)
