This bug was fixed in the package unity - 0.2.46-0ubuntu1

---------------
unity (0.2.46-0ubuntu1) maverick; urgency=low

  * New upstream release:
    - use get_basename instead of silly str manipulating, should fix (LP: #648625)
    - fix remaining issues when software is at start for non 3D detection
      (LP: #614088)
    - Fix duplicate ubiquity entry in UNE live session (was importing it from
      the GNOME desktop) (LP: #648827)
