Gksu launched applications inaccessible with Orca Screen Reader

[Attila Hammer]

Dear Developers,

My Ubuntu Saucy I experienced a very interesting issue, I tested only the problem with Orca master version.
I using GNOME Shell classic mode. When I installed the system, I used the access=v2 profile, because my wife using screen magnifier support.

When I launch any application with gksu command, Orca not reading the
application interface after I typed my password.
Example testcase with I reproduced always succesfuly the problem:
Open terminal, and run gksu gedit command.
If need, type your password.
Expected result: Orca reading Gedit interface.
Actual result: Orca absolute silent.

This situation not presenting any error message in the terminal.
To ensure this is not a mixed components related problem from Saucy, I upgraded my Saucy installation from git the at-spi2-core, at-spi2-atk and atk to 2.10 latest versions. Before upgrade I experiencing equals the issue.

Some time I experienced this issue when I launch any GUI application with sudo command prefix, or my normal user account.

To restrict not a buggy preference producing this issue, I keep a clean user folder my home partition and have a test user. If I login the testing account with not have any customized preferences, I experiencing this issue too when Orca running, gksu
command prefix absolute sure.

When I launching for example Gedit with sudo command, I see following message
in Terminal, now Orca for example not readed the Gedit application interface
with sudo privilege:
hammera@hammera-Satellite-L300:~$ sudo gedit
[sudo] password for hammera:

** (gedit:5029): WARNING **: Could not load Gedit repository: Typelib file for namespace 'GtkSource', version '3.0' not found
(gedit:5029): IBUS-WARNING **: The owner of /home/hammera/.config/ibus/bus is
not root!

The last line wrote file automaticaly creating my system, and automaticaly get my owner privilege the file.
I reported this bug Orca related with Bugzilla, link is following:
https://bugzilla.gnome.org/show_bug.cgi?id=719554

Joanie answered following this report:
"I can reproduce this in Ubuntu. I also cannot see/access the gksu-launched
gedit in Accerciser. In other words, this is not an Orca bug.

There is an old, open bug about gksu in Ubuntu filed against AT-SPI (bug
449159). That bug mentions the use of gksu-polkit. When I use gksu-polkit in Fedora, apps launched via gksu-polkit are accessible as expected. I do not see gksu-polkit in Ubuntu, so I don't know what you should do there. Perhaps file a
downstream bug against gksu or at-spi?"

The gksu-polkit package realy not available in Saucy the universe repository.
I experienced similar issue with Ubuntu 14.04 development release.
