I don't know if this is related, but I have s imilar problem under Xubuntu 15.04 that is still present in 15.10. Everytime I lock my computer and come back and unlock it, I have one or multiple "Authentication is required to change your own user data" popups. It seems to be dependant on the time the PC was locked. If it was locked for two or three minutes, there's only one or maybe two authentication boxes that appear one after another. However, if I come back after lunch (30 minutes), I once had to enter the password 18 times, but usually it stops after 10 popups. Highly annoying.

If I type my user's password the dialog will reappear with an empty entry field. If I click on the cross to close the window many times it will be gone, but reappear a few days later. I don't know what this window is for and it makes no difference whether I close it or leave it. I don't use the gnome keyring. This started with Ubuntu 15.04 or maybe with an earlier release, and is still there in Ubuntu 15.10, also on machines I did a fresh install.
