Now that I have some time to look at the problem it seems that the post-install
is failing with the following error:

  File "/usr/lib/python3/dist-packages/UnityTweakTool/section/spaghetti/gsettings.py", line 109
    antialiasing = gnome('desktop.interface’)
                                             ^
SyntaxError: EOL while scanning string literal

If you edit the gsettings.py file with gedit you can see that the end parentheses is showing
in pink instead of white.

Don't know if this is a problem with the patch file but somehow we are picking up an EOL
character which is causing the closing parenthesis to be shown as pink instead of
white(maybe interpreted as an EOL signal or something like that).

As far as I can tell the coding changes seem to be correct for the moving of the schema
from "xsettings" to "desktop.interface" but I am a noob so what the hell do I know.

If I can gather more information or anything let me know.
