Same here, I used to set screen brightness with something like

dbus-send --print-reply --dest=org.freedesktop.compiz /org/freedesktop/compiz-1/obs/screen0/brightness_values org.freedesktop.compiz.set array:int32:80

that has no effect now.
Also the examples at http://wiki.compiz.org/Plugins/Dbus have no effect or error out.

For example

$ python compiz-send.py vpswitch
Traceback (most recent call last):
  File "compiz-send.py", line 82, in <module>
    print '\n'.join(obj.list())
