Title:
  settings allow arbitrarily large user pictures which makes the user
  lock themselves out at lightdm.

Status in LightDM GTK+ Greeter:
  Fix Committed
Status in lightdm-gtk-greeter package in Ubuntu:
  Confirmed

Bug description:
  To reproduce on a fresh install of ubuntu mate 16.04 start lightdm-
  gtk-greeter-settings and authenticate to start editing lightdm
  settings. Please do not try to reproduce this on a production machine
  as it will involve locking yourself out of lightdm.

  In the settings for lightdm GTK+ greeter settings  select a really
  large image from a digial camera or high resolution screenshot as your
  user image that is larger than your screen resolution hit save and
  then log out.

  You will be taken to a lightdm screen that has a user image so large
  you cannot login.

  Description:	Ubuntu Xenial Xerus (development branch)
  Release:	16.04
  lightdm-gtk-greeter-settings:
    Installed: 1.2.0-0ubuntu1
    Candidate: 1.2.0-0ubuntu1
    Version table:
   *** 1.2.0-0ubuntu1 0
          500 http://us.archive.ubuntu.com/ubuntu/ xenial/universe amd64 Packages
          100 /var/lib/dpkg/status

  I would expect the greeter to check that it would not set such
  redicolous file sizes that block the user from logging in or at least
  provide a warning dialog that this could make you unable to login
  similar to things that cause data loss on a partition in ubuquity or
  gparted.

  As this prevents even loggin into guest session graphically. I did
  manage to get back in editing /etc/lightdm/lightdm-gtk-greeter.conf by
  hand with vim.
