SUMMARY In the subject. STEPS TO REPRODUCE 1. Ctrl+E opens Dolphin's window. 2. Navigate through a few (3-4) sub-folder levels to show some folder content. I experienced it only only once: the second and third time of opening of the same folder was success. It happened after the KDE update and reboot. ``` $ tail -n200 /var/log/pacman.log ...
