does not allow to login in when partition is full

[Viacheslav Kurenyshev]

I have a laptop with Ubuntu 12.04 (Fresh installation, not upgrade) 64 bits.
My home folder is encrypted.

It worked fine until a couple of days ago since I can't login in.

It boots normally, I enter login and password (does not matter Unity or Unity 2D), press Enter.
At this moment it seems that Ubuntu starts desktop, shows some messages and immediately goes back to login screen.
I attached the photo of this moment. One of the messages is "could not write bytes: Broken pipe". Photo is attached.

Mouse is working fine. No freeze on the screen.

I tried previous kernel as well as recovery mode. The system is up to date, no updates are available.

I can login using CLI (for example, pressing Ctrl+Alt+F1).

I don't know which package affected, but it's critical and it would be great if you could tell me which information I need to provide.

I am not sure after what it start happening.
Probably, I installed Cisco AnyConnect last time which worked great in all previous versions of Ubuntu (but I used only 32 bits before). I also installed VirtualBox.

I can provide a short video of the screen when I am trying to login.

Sorry for bothering you, but I found the cause of the problem.

I had 0 available bytes in my home directory. It did not allow me to login.
I reduced reserved-blocks-percentage to 0% of /home device. It got me additional 2.8G of space.

But I think the bug still exists.

I should be able to login and does not matter how much space I have left (0 bytes or 10G).
Maybe, we need to change the title of the bug.

Reading the bug description lightdm seems to load fine but the session itself fails to start and send you back to the login screen, that's rather a gnome-session issue then

seems like bug #873368
