I think there is a misunderstanding here: The initial problem (tool
bar icons not updated according to :active condition) still exists.

[ As already pointed out in a previous message, I agree with Chong
  Yidong that this problem should not block the release.  (This bug
  has already been there in Emacs 21.1 (and version 5.9 of Gnus
  bundled with it) and I don't recall any complaints about it.) ]

As a workaround for Emacs not updating the icon according to the :active
condition automatically, I added a `redraw-frame' call inside
`run-with-idle-timer'.  Kim suggested to use `force-window-update'
instead which didn't appear to work for me.  But `force-window-update'
does work as good as `redraw-frame' in the workaround.

What I have in the relevant mode (gnus-group-mode) now is:

      (add-to-list (make-local-variable 'post-command-hook)
                   'gnus-group-redraw-check)

(defvar gnus-group-redraw-when-idle 2
  "When non-nil, redraw the Group buffer frame when idle.
Internal variable.")

(defun gnus-group-redraw-check ()
  "Check if we need to redraw the frame."
  (when gnus-group-redraw-when-idle
    (run-with-idle-timer gnus-group-redraw-when-idle
                         nil 'force-window-update)))

Bye, Reiner.
