zipapp file path conflicts

[francisco]

After running a packaged application (with zipapp.create_archive) which uses the latest python-openstackclient library, when using OpenStack functionality there is a path related exception, this only occurs on the packaged application, everything runs fine otherwise (IDE etc..).

Stacktrace:

    Catch NotADirectoryError error

    Per the documentation [1]:

      exception NotADirectoryError
        Raised when a directory operation (such as os.listdir()) is
        requested on something which is not a directory. On most POSIX
        platforms, it may also be raised if an operation attempts to open or
        traverse a non-directory file as if it were a directory. Corresponds
        to errno ENOTDIR.

    Apparently creating a packaged application can cause this issue. There's
    no harm in ignoring it so do just that.
