Keyboard layout switcher ignores settings

[Fake51]

In Keyboard Layout settings, you can choose "Allow different layouts for individual windows". This used to work just fine (in 12.04 and before) but recently in 12.10 a change has been introduced that makes the keyboard layout switcher (using a hotkey) ignore this setting.

In effect, when I use my hotkey to switch keyboard layouts, the layout is switched not just for the active application but all applications at once. I typically see this when I am in an application like Thunderbird and switch to another keyboard layout to compose a message, then switch to a console (that was already open) where I suddenly input in a different language than when the console opened.

What I expect to happen:
the keyboard layout switcher only affects the currently enabled window

What happened instead:
more windows had their keyboard layout effected, not just the active window

I can narrow this down more actually - it doesn't happen for everything, seemingly only on some windows.

I can reproduce it with new windows with text areas where nothing has been entered - so opening a compose window in thunderbird, or a blank page in gedit, then switching keyboard layout using the keyboard combination, will trigger the bug.

In other words it seems as if the keyboard switcher gets confounded by new windows, and instead of switching keyboard layout for just that window, it does it overall.

Also, the keyboard layout indicator fails to update - which makes me think this bug is related to, if not a double of, https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/948763

Interestingly, if after I switch keyboard layout the first time in a new window, I then switch again until I hit the "right" keyboard layout (i.e. making a full round), then the switch does not carry over to other windows, but is working as it should (meaning: I'm only switching layout for that single window).

Status changed to 'Confirmed' because the bug affects multiple users.
