Testing further the problem seemed to be something in konsole settings. I've been in the habit of hiding the menu bar, and there has been some bug with respect to that as well. Now after few trials back and forth I managed to make the menu bar stay hidden in new terminal, and the KDEinit error disappeared as well.
