This post is older than a year. Consider some information might not be accurate anymore.
The evince pdf viewer under Ubuntu 14.04 LTS didn’t work anymore, after I have moved my home directory from /home to /data/home
A symlink wasn’t sufficient.
After looking up https://bugs.launchpad.net/ubuntu/+source/evince/+bug/1433165 the solution is simply to run
sudo dpkg-reconfigure apparmor
and configure the new home directory to /data/home/. The last / is important!
