Parley - "Writing file 'Untitled' resulted in an error. File is not writeable"

When starting Parley i get a bunch of alerts

Error in file /usr/share/parley/plugins/example.py at line -1:Failed to determine interpreter for scriptfile "/usr/share/parley/plugins/example.py"
Backtrace:

and then when i try to create a new vocab file i get this

Writing file "Untitled" resulted in an error. File is not writeable

however, all works fine if i open an existing vocab file and edited it and save it???

BTW: This is a brand new installation of LEAP 42.1

Any ideas??

… and in investigating further by opening up that particular script i.e. /usr/share/parley/plugins/example.py, it can be seen that it calls the interpreter kf5kross


#!/usr/bin/env kf5kross
# -*- coding: utf-8 -*-
import Parley
import Kross

… and by doing a search find not only is it not installed but does not appear in the repositories that i have enabled:


openSUSE-42.1-0
Main Repository (NON-OSS)
openSUSE-Leap-42.1-Update
google-chrome
Adobe Flash Plugin
Packman Repository
nVidia Graphics Drivers

… even if it is clear that ‘kross’ version 5.16.0-3.1 is installed

But whether or not these facts point to the file not writable issue raised by this thread is unclear???
