i know that this seems to be a gnome bug, but i got the same issue within kubuntu 12.10
when activating the mouse focus policy "focus under mouse" or "focus strictly under mouse" in the windows property settings alt+tab stops working.
using any other focus policy enables alt+tab again.
maybe this information might help to fix the gnome issue
