changing 'switch language keys' no longer working in 13.10

Question

I have Ubuntu 13.10 installed. from Text Entry Settings I added Arabic to keyboard layouts then tried to change the 'Switch to next source using: ' field. I tried to set it to Shift+Caps Lock and Alt+Shift and other combinations but no luck, It does not change,just leaves a blank field.

I tried to change the keys from Keyboard Settings > Typing > Switch to next source, same results, whatever combinations I try it leaves the field disabled.

how do I change the keys and fix this problem ?? I never had this problem in any of previous Ubuntu releases.

Hint: I had Ubuntu 13.10 when it was still in Beta and then updated to the last release, This problem existed all along. I don't know if that can be relevant but just in case.

Solution

This has been filed as a bug report: Hotkeys not functional in non-latin keyboard layout in 13.10 For now, the bug report gives the following workaround:

Workaround for some system hotkeys and two layouts (english and non-latin): rebind all hotkeys in your local layout. For example instead of ctrl+alt+t use ctrl+alt+τ (greek tau). That hotkey still work with english layout. If you use english and two different non-latin layouts this workaround helps only with one of them.

You could also use the indicator on the menubar to switch layouts rather than the hotkeys.

Update:

As mentioned by levesque, there is another bug listed that addresses this issue. The solution provided in the bug thread is as follows:

A PPA which should provide some relief for this issue is available at https://launchpad.net/~attente/+archive/modifier-only-input-switch. To install:

sudo add-apt-repository ppa:attente/modifier-only-input-switch
sudo apt-get update
sudo apt-get upgrade
(log out, log in)

If the packages improve the situation for you, you can pin them using:

sudo apt-mark hold compiz
sudo apt-mark hold gnome-settings-daemon
sudo apt-mark hold unity

If the packages don't work for you, you can purge them using:

sudo ppa-purge ppa:attente/modifier-only-input-switch

@chaskes forgive me, I'm not that experienced with linux. Should I wait until this bug fix is applied in an update or try to install or run it myself? if the second, How?

Ignore the answer below, this is the bug report you are looking for : bugs.launchpad.net/ubuntu/+source/indicator-keyboard/+bug/…

I believe this is the bug, and not what you linked to - bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug‌​/… - FYI, I installed a custom patch (don't remember which), and now I can set the combo to Super-Shift. (Nothing else works/worked, not Super-Space nor Alt-Shift)
