Hello I've recently upgraded from 13.04 to 13.10 64bit.
I'm running AMD graphics with the proprietary drivers.
I have two user accounts. Mine(administrator) and my girlfriend's(standard)
My girlfriend clicks "switch user" from my lock screen and logs in fine.
I then try to click "switch user" from her lock screen and everything goes black. Then the monitor blinks on and off with just a single cursor. I have no way to access the terminal, the system is unresponsive and I have to hit the power button. Even ctrl + alt + f4 or ctrl + alt + t doesn't get me a terminal. When I press the power button on my system, it does start printing out the shutdown sequence on the monitor.
Here is my .xsession-errors
Script for ibus started at run_im.
Script for auto started at run_im.
Script for default started at run_im.
Here is hers:

I found some advice in a forum to look for at-spi2-registryd in my system logs. Perhaps it will be useful.
executing this: sudo grep -r at-spi2-registryd /var/log/*
produces this:

Here are my logs lightdm logs:
Any ideas what is going on?

I fixed the problem but I'm not sure what caused it.
I renamed /var/lib/lightdm/.Xauthority to /var/lib/lightdm/.Xauthority-bak I did the same thing in my home directory.
Then I restarted lightdm
Works fine now. One of the files was corrupted, but I'm not sure which one fixed it.
