I have the same problem after an upgrade to 15.10. running a gnome3 session here.

One other report of this problem is here: https://askubuntu.com/questions/562355/seemingly-random-authentication-is-required-to-change-your-own-user-data

The "solution" posted there however doesn't seem right to me (preventing PolicyKit Authentication Aagent from starting).
