keyboard layout fails to be different for individual windows

[Péter Prőhle]

My case is a close variant of the following two bugs closely related to each other:

        https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/885730

        https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/622965

My usual setting in "system settings ..." / "all settings" / "Keybord layout" is as follows:

        "allow different layout for individual windows" (this allows me to fluently work in different languages in parallel)

        "new windows use the default layout" (this enables me to concentrate on the new window instead of the last one)

Bug #885730 deterministically reproducable in my case: open firefox, switch to hungarian but the indicator remains ENG. Then switch back to ENG, and again to HUN, and starting from this second time not only the keybord input, but also the indicator reflects correctly the HUN state. This problem never happens working in terminal window. I do not use non-ENG in other applications, only in terminal or in firefox.

Bug #885730 has now 4 substatuses: 2 "fix release" dated 2012-03-16, 1 "invalid" and 1 "Won't Fix", this latter I hope is not true for the current and future releases. My case is essentially different from this bug: my case looks deterministic and restricted to the first switches. After the third switch indicator shows the state correctly. However, in normal work, there is never a second and third switch, hence this bug causes essentially ALWAYS a missleading language indication.

Bug #622965 dated 2010-08-23 is even older, and my case is essentially different again, that in contrary to the old deterministically reproducable bug, right now, I can not reproduce the bug during this bug submitting period. While this old bug affects me, whenever I work in normal: usually I have a single terminal window, or rarely a single firefox window, and when I want to open the other kind of window, then the bug is there, but for later changes and new window, the bug is usually not there.

The reason why I can not reproduce the bug during bug report is, that I can not close the firefox dufing the preparation of the bug report. What if the problem in my case is in the cooperation of firefox and the graphical event handling frame system?

I use now 12.10 with all the possible updates, including proposals.
