Since I have installed Konversation, it keeps launching after a reboot and login. SOFTWARE/OS VERSIONS Operating System: Manjaro Linux KDE Plasma Version: 5.18.5 KDE Frameworks Version: 5.70.0 Qt Version: 5.14.2
Does this occur even if you have quit Konversation (Ctrl+Q)?
I just noticed that clicking on "close" or pressing Alt+F4 does not "close" the application but only Konversation's window. Ctrl+Q did the trick.
