Comment 49 for bug 885730

@charles: I can only add that you need to enable per-window layouts in g-c-c to better reproduce it. In such cases, the indicator doesn't correctly update its state on windows switching.

Speaking about technical details, our patched g-s-d watches for "X-state-changed" signal (there are 2 callbacks for it — gkbd_configuration_state_callback() and state_callback() — both result in correctly updating the menu), but it seems that this signal isn't emited on window changes, so we should probably fix it or handle window switches separately.
