After upgrading from Ubuntu Raring to Saucy, the new Keyboard applet changed my keyboard shortcut for cycling between keyboard layouts to Super+Space, but this new shortcut doesn't do anything. When trying to set my old shortcut (Shift+Caps Lock), it interprets that as Mod4+Super+Hyper+Space.
Is this a know problem, and is there any way I can get my old shortcut back? I need to cycle between 3 different keyboard layouts frequently (sometimes several times an hour), so having to use the mouse for this is a major regression in my work flow.
