Switching from workspace 1 to workspace 4 by pressing alt-ctrl-left and from workspace 4 to workspace 1 by pressing alt-ctrl-right works the way it should. This is consistent with what Gregg describes in (8).
I guess, that the shortcuts are processed twice. Once by Gnome as it would with desktop-effects disabled and once by the cube workspace switcher.
