[Cosimo Cecchi <cosimoc src gnome org>]

commit 376f9ba0bdd25794a6bd2a57caa760b8d2cbb32d
Author: Cosimo Cecchi <cosimoc gnome org>
Date:   Mon Jun 7 15:30:00 2010 +0200

    Support relative paths in NautilusLocationEntry.
    
    This also adds a custom 'activate' implementation which converts a
    relative path (if present) to an absolute one.
