Can't start shifter_server in Debian Lenny

[R4v3n]

Hi guys,
I installed shifter from the debian lenny repository (v 0.9.19) on my Lenny.
The application start, but I can't start the shifter_server because of the GIO module of python, because GIO is introduce in PyGTK 2.14, and Lenny run with the 2.12.

To be sure, I paste the error :

* Caught exception: <type 'exceptions.ImportError?'>: No module named gio
Traceback (most recent call last):

File "/usr/lib/python2.5/shifter/server/controller.py", line 939, in main

server.start()

File "/usr/lib/python2.5/shifter/server/controller.py", line 216, in start

self.start_menu_monitor()

File "/usr/lib/python2.5/shifter/server/controller.py", line 337, in start_menu_monitor

import gio

ImportError?: No module named gio
2010/30/06 16:24:51 ShifterController?.stop_reactor() Can't stop reactor that isn't running.

So, is there a solution, or I need to upgrade to testing to use the shifter_server ?

Thanks !
