system-config-samba.py crashed with SystemError in __init__()

Binary package hint: system-config-samba

well, it's very simple, i want to start the client of samba, and, it crash. I cannot see nothing, and the service doesn't work. I use Ubuntu 8.04, and the ultimate version of samba. This sistem has been installed, since 2 hours, more or less. It's a very old laptop, but i have it in a new desktop, and samba doesn't work too. I use Ubuntu at laptop and Kubuntu at desktop.

I can't solve it at forum, but i see the same problem in too many people.
