There is two "language preference" drop down menu in the "side bar". Only one of them is working.
This is with internet explorer 8.0 and Gallery 3.0 git (pre-RC1).
I think, though I'm not sure as I'm not able to duplicate the duplicate language settings just other blocks that it's related to this ticket I just created:

Thank you so much. It works after moving thing as described in the ticket.
