Just to provide some additional background information. The reason why those authentication popups are triggered is Bug #606092 [1]
As a result of this bug report, the packagekit policy was changed to require admin priviliges to do system updates. gnome-settings-daemon though expects that such updates can be done silently/unattended, i.e. without user interaction. See also the comment in [2] So, what Joss has done is disable the auto-updates in gnome-settings-daemon.
