That's not one we've encountered before, but if the keyboard shortcut is working in any of the applications, everything we have control over is set up and working as expected. (As far as I know.)

This might be worth stopping by the genius bar at your local Apple store, if that's possible. If it does get figured out, please let me know - I'd love to modify the sticky thread with info on what's going on in case it helps other folks!
