Yes, it also happens in a guest session. I'm attaching the corresponding ~/.xsession-errors

I do not use a background picture on the desktop:
$ gsettings get org.gnome.desktop.background picture-uri
''

$ gsettings reset org.gnome.desktop.background picture-uri
$ gsettings get org.gnome.desktop.background picture-uri
'file:///usr/share/backgrounds/warty-final-ubuntu.png'

This gives back the default background picture but the Brightness and Lock tool still does not show the brightness slider.
