First of all, could you try the following in a terminal:
1) apt-get source system-tools-backends
2) cd system-tools-backends-2.6.0
3) ./test-backends.in UsersConfig
...and post the output
Also, could you have a look for any errors in /var/log/syslog or /var/log/messages, particularly related to DBUS. Could you also try booting without 'quiet' and 'splash' to see if there are any error messages during boot.
When you run users-admin, you should see a process with the command line '/usr/bin/perl /usr/share//system-tools-backends-2.0/scripts/SystemToolsBackends.pl -m UsersConfig' appear, as this service should get started by DBUS when you launch users-admin. Can you tell if that is happening?
Sorry for the delay in getting back.
