Dear Maintainer, When finishing a KDE session will be displayed in the journal core dumps caused by kactivitymanage and kdeconnectd. The problem is reproducible at any time. Below is an excerpt of the systemd Journal: ------------BEGIN---------- Sep 21 09:16:50 bluesky systemd-coredump[6794]: Process 4949 (kdeconnectd) of user 1000 dumped core.
