[Craig Keogh <cskeogh src gnome org>]

commit 1b0877f5c13a0eed98beb24ed23578dea16102bb

    execute on systems without python-dbus as well
    
    * jhbuild/utils/trayicon.py: some systems (e.g. lots of scratchbox setups)
      don't have many python bindings available/installed. This commit makes
      jhbuild work in such environments as well
