I'm getting errors in ~/.xession-errors. I'm running ubuntu 12.04

Many apps fail to run without mention of problems in the .xsession-errors file. I looked around and tried to resolve issues myself but failed so far.

I have to say it's possible that the issue is related to me mounting /home on another partition. (I say possibly because stuff worked ok for a while.)

Fortunately my .xsession-errors file is small enough to post here. Thanks in advance for the help:
