From the bug report I linked to, it sounds like some people resolved this issue by various means:

  • Reinstalling all gnome-keyring packages

  • Running

    sudo gedit /etc/lightdm/lightdm.conf

    in a terminal, then removing the autologin-user= YOUR USERNAME line and running

    sudo shutdown -h now
  • Killing plexmediaserver, if installed
  • Doing a fresh reinstall of the whole OS

I have not tried any of these methods myself (I was previously affected but not anymore), so I cannot say from personal experience which of these would likely work for you. Be sure to backup any data before trying any of these suggestions.
