self.root not guaranteed to be set

[Nathan Osman]

In setup.py:160, the following line references "self.root":

    desktop_file = move_desktop_open(self.root, target_data, self.prefix)

However, the base class for the install command, "distutils.command.install.install", doesn't always set "self.root". In fact, the default value is "None". This leads to an exception during installation if "self.root" is not set:

      File "setup.py", line 98, in move_desktop_open
        old_desktop_path = os.path.normpath(root + target_data +
    TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

I'm afraid this is going to take quite a bit of time to refactor, time I won't have until at least August.
