Keyboard layout doesn't show in GNOME Shell session (again)

[أحمد المحمودي (Ahmed El-Mahmoudy)]

Since I upgrade GNOME Shell from 3.4 to 3.6, the keyboard indicator is blank
and doesn't display the codename for the active keyboard layout.

I have enabled english & arabic keyboard layouts. I have the following
settings:

$ gsettings list-recursively org.gnome.desktop.input-sources
org.gnome.desktop.input-sources current uint32 0
org.gnome.desktop.input-sources show-all-sources true
org.gnome.desktop.input-sources sources [('xkb', 'xkb_layout')]
org.gnome.desktop.input-sources xkb-options @as []

I checked the code in /usr/share/gnome-shell/js/ui/status/keyboard.js, and I
reached the '_inputSourcesChanged' method in 'InputSourceIndicator' class, the
program does run the following code:

            let [type, id] = sources.get_child_value(i).deep_unpack();

            if (type == INPUT_SOURCE_TYPE_XKB) {
                [info.exists, info.displayName, info.shortName, , ] =
                    this._xkbInfo.get_layout_info(id);

I checked the 'id' variable, and its value was 'xkb_layout' (as per the
settings).
Yet the output of the last statement { this._xkbInfo.get_layout_info(id) } is

[ false, null, null, , ]

Can anyone help with this issue ? I'm not sure if its a bug in GNOME Shell, or
something wrong with my system or settings.

Note: This issue has been in Ubuntu precise & it is still happening in raring, that I am running right now

I found out that I done a mistake of setting the second string 'sources' key to the literal string 'xkb_layout' instead of the layout codename.
So, I changed the setting as follows:
$ gsettings get org.gnome.desktop.input-sources sources
[('xkb', 'us'), ('xkb', 'ara')]

Now, the keyboard indicator does show the different layouts, and defaults to
the english 'en' layout. Yet, if I select the arabic layout, it doesn't
actually change the layout, yet it does update the indicator to display 'ar'
instead of 'en' (even though the active layout is arabic 'ar').

Also if I actually changed the layout using a hotkey, the keyboard indicator
doesn't update to reflect the currently active layout.

In https://bugzilla.gnome.org/show_bug.cgi?id=695723#c10 , upstream said that this bug is caused by some patch by downstream.

This problem does not happen with Unity, since it doesn't rely on the keys under org.gnome.desktop.input-sources

[أحمد المحمودي (Ahmed El-Mahmoudy) (aelmahmoudy)]

This problem is actually two-fold:

1) Adding layouts via GUI (gnome-control-center) doesn't modify the appropriate key under org.gnome.desktop.input-sources

2) Even when I manually add the layouts via org.gnome.desktop.input-sources 'sources' setting, the layouts don't actually work !!

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