When launching emacs from an xterm or an urxvt terminal in my fluxbox
window manager, I always get annoying output to stderr:

  mjambor@mymachine:~$ emacs
  Activating service name='org.gnome.GConf'
  Successfully activated service 'org.gnome.GConf'

it is not happening when I run emacs-gtk or emacs-x11 directly, so it
must be coming from the alternative picking script /usr/bin/emacs.
Running bash -x /usr/bin/emacs to find out which line does it, it is
apparently the following one:

  exec -a /usr/bin/dbus-run-session /usr/bin/dbus-run-session --
/usr/bin/emacs-x11

So I tend to think this is a dbus bug.  Technically it is a minor
issue but it sure is very annoying, so please make it go away.
