In "System Settings" ("Configure Desktop) applet In "Personalization" block - "Account details" one can add some personal information to it's own account - email, profile picture and (i assume) change a password, although once in password field i'm getting pop up window to enter and re-enter new password without "enter old password first" field.
But anyway, when i try to add profile picture i am being asked for root password. Although when i click on "cancel" my picture still being assigned.
I do understand root (admin) password request if i would try to change anything for another user, but it seems to me excessive to be asking root password for anything concerning my own account.
Could you please check if you experience same behavior, and if yes i would like to submit a bug request.
