Yes, I recall Detlev putting me right on other issues with PyKDE4 - requires putting a tick on one of the configuration boxes of eric. I am using eric5 (that's the python3 version). I will install the newest version and look for the "box to tick" - Detlev is a very helpful guy! The message does occur exactly the same way when the scripts are fired from CLI. I should try it on a gnome desktop in order to avoid PyKDE4. IIRIC, PyKDE4 is not windows compatible. And that is a problem if one wants to ensure compatibility with Windows - I do not really care about that. Too late for me :).
