Click on System tab and then users and groups starts the users-admin program.

Throws a cannot start configuration error in a dialog box with only an OK button.

Work around is to start a process that requires admin authentication then restart. This seems to fix it for the rest of the time that the user is logged in.
If admin authorisation has already been requested for a different process the error is not seen.

On my set-up the admin authorisation is rescinded when the requesting process terminates.

Ok next day, I've attached the screen shot and the current ~/.xsesseion-errs although there's nothing in there to indicate a problem

$ sudo apt-get install --reinstall gnome-system-tools
did fix that error for me

Thanks for the report. Seems to be the same problem as bug 411533. Could you try to fix used in that comment?
