This bug was fixed in the package gnome-desktop3 - 3.6.0.1-0ubuntu2

---------------
gnome-desktop3 (3.6.0.1-0ubuntu2) quantal-proposed; urgency=low

  * Add Replaces from libgnome-desktop-3-4 to libgnome-desktop-3-2.
    Unfortunately this shared library ships binaries in an unversioned path.
    If the upgrade ordering is such that libgnome-desktop-3-4 is unpacked
    before libgnome-desktop-3-2 is removed then dpkg will error due to file
    overwriting. The long-term solution to be implemented is to move these
    binaries to their own package and to alter consumers to depend thereon.
