If I switch session from GNOME Fallback session to any Unity session, and switc back the session with GNOME Fallback session, some custom defined keybindings are deleted after log in operation

[Attila Hammer]

Dear Developers,

I generaly using Oneiric release with GNOME3 fallback session with Orca screen reader.
Because some oldest general GNOME keybindings is not defined factory level, I defining following keystrokes:
ALT+F1: Show panel main menu
ALT+F2: Show the run dialog:
SUPER+D: hide all windows, and switch desktop.

I want desting an Unity a11y modified version from a developer request, so I changing session to Unity 3D session (ubuntu session).
Because lightdm is not accessible yet with Orca screen reader, I edit /etc/lightdm/lightdm.conf file, and putted following content the configuration file:

[SeatDefaults]
xserver-layout=hu
autologin-guest=false
autologin-user=hammera
autologin-user-timeout=0
autologin-session=lightdm-autologin
greeter-session=unity-greeter
user-session=ubuntu

After I restart my system, I doed the required test, and want switch back the GNOME3 fallback session, so I simple replace the user-session=ubuntu line with user-session=gnome-fallback line, and restart my system again.
The surprise is happening after the login operation, my prewious defined custom keybindings is lost. I unable to present panel menu with ALT+F1 key combination, unable to present the run dialog with ALT+F2 key combination, and unable to go to the desktop with SUPER+D key combination.
When I looked the defined keybindings in GNOME Control Center the keyboard preference tool /keybindings section, some keybindings are disabled again (present panel menu, present run dialog), and I think the hide all windows related keystroke is changed with CTRL+ALT+D keystroke. Sorry if I not translate right this items correct english name, I using the system with hungarian locale.

Why happening this problem, and why owerwrited my custom keybinding settings after session change and session change back? Unity stores equals place the own keybindings and owerwrite my custom keystrokes?

Reproducation steps, I always reproduced this issue:
1. If not installed, install gnome-session-fallback package after you enabled with universe and multiverse repositoryes.
2. Switch GNOME Fallback session after you logged out, log in the new session, and define the described keybindings.
3. Switch any unity session after log out, log in, and log out again the new session.
4. Switch back GNOME fallback session, and log in again. If you are reproduced this bug, your prewious defiled three keybindings is lost.

I will be sending screen shot to startup keybindings preferences, and the new preferences after I doed this test again.

Ok, I don't no why, but when I switch back with GNOME3 fallback session,
the ALT+F1 and ALT+F2 keybindings are not losted now.
This is happening perhaps because I installed proposed updates?
You possible reproducing my issue?
I using Oneiric since beta2 installation, and this day morning I
installed proposed updates.
