Comment 74 for bug 150702

Maverick is affected as well, it doesn't matter if compiz is active or not. Just as others pointed out, the problem can be avoided by not using Alt+Shift as the keyboard layout switch. The same kind of problem arises when one wants to use Ctrl+Shift short-cut for keyboard layout switching though. This time, it affects cycling backward between panels in Chrome/Firefox.

Any chance to get this one fixed anytime soon :-)?
