Have a slightly different though clearly related problem:
I disabled all switching of keyboard layouts and have just a single adjustment in the gnome-tweak-tool:
Namely, in 'Typing' I set 'Switch to another layout' to the button 'left Win (while pressed)'. Hence I would expect to have the layout switched whenever I keep this button pressed. Layout indicator does not switch also on other window managers I used besides Gnome but the actual keyboard layout switches.
Interestingly, it works properly if I switch manually to the secondary layout, which is from English (primary) to German (secondary), and then press the left Win key: the layout switches back to English while pressed. The other way around however does not work. When English is set as standard and then Win key is pressed, nothing happens.
Using Ubuntu 14.04 LTS with Gnome 3.10.4
