I've recently upgraded to Ubuntu 13.10 which has a known bug that makes it impossible to change keyboard layout via Alt+Shift. I installed this patch which made it possible to switch layouts again.
The problem I'm facing now is that it is still impossible to switch keyboard layout when I lock (Ctrl+Alt+L) system and press Alt+Shift. This way if I lock system with wrong layout enabled, I can't switch it to enter the password and unlock PC. I can still change layout by clicking on the layout indicator. I'll be thankful for suggestions on solving this.
I'm aware that this is due to a bug, but how can I work around this bug in the meantime?

There is workaround. if you want to use only control keys combination like ctrl+shift or shift+alt to switch between sources you could set "Switch to next source using" to only control keys combination like shift+alt while set "Switch to previous source using" to your combination + space and use it only in case of the lock screen.
