gajim error

[lostson]

Hello All 
 I am trying to use gajim but when starting gajim i get this error

ImportError: could not import gnomecanvas
ImportError: cannot import name DockItem from bonobo.ui
Traceback (most recent call last):
  File "gajim.py", line 1923, in ?
    cli.set_restart_command(argv)
AttributeError: '__main__.GnomeClient' object has no attribute
'set_restart_command'

 Am I missing a dependency or something ? Does anyone know how to fix
this? Thanks.
