can't launch gwibber

[Nizar Kerkeni]

Binary package hint: gwibber

On Natty the messaging menu indicates the number of new messages for gwibber but when clicking on it nothing happens, gwibber is not launched. When trying to launch it from the command line I got this :
nizarus@vaio:~$ gwibber
Traceback (most recent call last):
  File "/usr/bin/gwibber", line 55, in <module>
    from gwibber import client
