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

[Paul Cook]

Binary package hint: system-config-samba

Application crashes immediately on launch. No window appears on screen. Reproducable.
Ubuntu 8.04 beta
samba 3.0.28a-1ubuntu3 installed
I think gvfs was also installed on automatic updates this a.m.

I am able to browse my QNap 209 NAS shares, but was attempting to access shares to change the workgroup name from the default of WORKGROUP.
