I have no idea who's to blame. But the effects are devastating. Reproducible: Always Steps to Reproduce: 1. Select a line of text in Konsole 2. Switch to LibreOffice (5.1.1.2) 3. Press ctrl-shift-v for paste-special Actual Results: Desktop Session vaporizes and SDDM appears to login. Expected Results: A dialog asking in what format I want to paste the Konsole clipboard contents. I don't blame Konsole, I just don't have any clue where to start reporting. I only know that paste-special from Kate or any other application works as expected. My work-around now is pasting in Kate, re-selecting the text and then past-special in LibreOffice. The reason I need paste-special is that pasting from Konsole adds the Konsole font markup that I don't want in my document.
