The bug affects the keyboard layout system tray applet as well as the locked screen dialog if the system is so configured as to lock the screen upon the closing of the laptop lid.  Furthermore, to address any concerns that this might be a bug with X, I would like to state that I could not
reproduce this bug with Cinnamon which itself runs atop of Gnome 3.2.

The issue involves the following.  Upon closing and then subsequently opening the laptop lid (Dell XPS M1530), the keyboard layout indicator in the system tray fails to update.  In addition, if I would need to log back in from a locked session induced by the closing of the lid, I would not be presented with a flag/label representation of the current layout.  In either of these cases, I am still able to issue changes to the layout via a global shortcut (set to left win), or via the mouse for the case of the applet only.  These changes, however, are not reflected by either the applet or the locked screen dialog.

This issue with the system tray icon can be remedied temporarily via any committed change to the layout system.  However, upon closing the lid again, the buggy behavior returns.

Lastly, simply locking the screen in a session that never had the lid closed (or in a session where the issue was corrected as above) produces the expected results; namely that the keyboard layout is indicated (either as a label or as a flag).  Furthermore, again in the same context, the keyboard layout applet works as expected.


Reproducible: Always

Steps to Reproduce:
1.  Start a session
2.  Close the laptop lid.
3.  Open the lid after say 5 seconds.
4.  If you need to unlock a session, note the absence of the layout indicator in the dialog.
5.  Change the layout with your global shortcut.  Test the actual change of layouts in a text editor to verify.
6.  Commit any change to the layout system (say change from Flag to Label etc); and note that the problem has gone away (but only temporarily).
7.  Repeat step 2 through 6 to verify.
Actual Results:  
After the lid has been closed and subsequently opened, any changes to the layout issued via a global shortcut produces entries in .xsession-errors whenever the layout is not the first in the list.

Thus for example, I have added the following layouts in the order listed:  US, HU, GR and DE.  The .xsession-errors had the following entries after I repeatedly switched between the keyboard layouts, after having closed the laptop lid:

Switch to HU:
kded(4943) X11Helper::getCurrentLayout: Current group number 1 is outside of current layout list ("us")
kded(4943) X11Helper::getCurrentLayout: Current group number 1 is outside of current layout list ("us")
Switch to GR:
kded(4943) X11Helper::getCurrentLayout: Current group number 2 is outside of current layout list ("us")
kded(4943) X11Helper::getCurrentLayout: Current group number 2 is outside of current layout list ("us")
Switch to DE:
kded(4943) X11Helper::getCurrentLayout: Current group number 3 is outside of current layout list ("us")
kded(4943) X11Helper::getCurrentLayout: Current group number 3 is outside of current layout list ("us")
Switch to US:
No entires added to .xsession-errors
Switch to HU:
kded(4943) X11Helper::getCurrentLayout: Current group number 1 is outside of current layout list ("us")
kded(4943) X11Helper::getCurrentLayout: Current group number 1 is outside of current layout list ("us")
etc ..., where, these entries would repeat cyclically.


Expected Results:  
The system tray keyboard layout applet should always indicate the current layout when it is switched.  In addition, if the session gets locked via the closing of the laptop lid, the current layout should be indicated in the locked screen dialog.
