Bug Description
To reproduce on a fresh install of ubuntu mate 16.04 start 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

Installed: 1.2.0-0ubuntu1
Candidate: 1.2.0-0ubuntu1

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/

Same here. Workaround: Tab 3 times, enter pw, Enter.
Pretty lame.
