Bug Description

After today upgrade, any time the brightness change, by manual action or by the power settings to dim the screen on battery I get a popup to authorize gsd-backlight-helper to run as superuser, looking at the ps output I see:

pkexec /usr/lib/gnome-settings-daemon/gsd-backlight-helper --set-brightness 15

Let me know if there is any extra info I can provide.

Sorry - Bugs seem not to be fixed. Ubuntu 12.04 (Unity) still asks the password.
