I think it might be because the libxklavier engine is reporting it can do a maximum of 4 keyboard layouts http://xlibs.freedesktop.org/xkbdesc/doc/libxklavier-xkl-engine.html#xkl-engine-get-max-num-groups no idea where it gets this from, but the limit does not appear to be in gnome-control-center itself

I have added four keyboard layouts and can no longer add any more. This seems a rather arbitrary limit on the number of keyboard layouts allowed. Can it be increased?
