[Federico Mena Quintero <federico src gnome org>]

commit 1093e1433eeebbf5eed71bc9dc0a8fda3a051b35
Author: Federico Mena Quintero <federico gnome org>
Date:   Wed Sep 7 17:55:21 2011 -0500

    Add gtk_places_sidebar_set_current_uri()
    
    And remove the code that updated the current URI automatically based
    on a NautilusWindow.
