Crouton: xfce chroot giving error on start with ASUS C100P

An error window pops up right when the startxfce4 command is put in saying:
"Unable to contact settings server" 
//bin/dbus-launch terminated abnormally with the following error: EOF in dbus-launch reading address from bus daemon

and followed by a second error message that is:
"unable to load a failsafe session"
Unable to determine failsafe session name. Possible causes:xfconfd isn't running (D-Bus setup problem); environment variable $XDG_CONFIG_DIRS is set incorrectly (must include "/etc"), or xfce4-session is installed incorrectly.

How should I go about fixing this? 

[egg1st]

I have the same issue, but I've been able to fix this part. The dbus_contexts file is missing

I had to create the file path first
sudo mkdir /etc/selinux/targeted/contexts

then to create the file with the contents
sudo cat "<busconfig><selinux></selinux></busconfig>" > dbus_contexts

You can see another example of the file here:
https://selinuxproject.org/page/PolicyConfigurationFiles#contexts.2Fdbus_contexts_File

However I now get a different issue

I found a solution. The release we had installed was "precise", but the latest stable release is "trusty". Worked first time.

You can see the current relases by running, and "trusty" is the most recent which is supported.
sh ~/Downloads/crouton -r list

So I just installed "trusty" instead. You can force the installation of a release by using:
`sudo sh ~/Downloads/crouton -r trusty -t xfce

If you want to encrypt it then it's
`sudo sh ~/Downloads/crouton -r trusty -e -t xfce

Make sure you remove the "precise" installation first
`sudo rm -R -f /usr/local/chroots/precise

Otherwise you'll need to specify the chroot instance everytime.
