SUMMARY Weirdly 'coredumpctl' shows no crash for plasma, no backtrace is generated by 'gdb plasmashell' > 'thread apply all bt'. Konsole only shows some error messages. STEPS TO REPRODUCE 1. start Wayland session 2. open some windows (dolphin, ksysguard, discover, etc) 3. minimize all windows 4. right clck on some entry in plasma panel and do NOT move cursor 5. wait some miliseconds to appear the tooltip of the right-clicked entry 6. while both tooltip and context menu are visible, click the hovered entry in plasma panel to unminimize the window OBSERVED RESULT plasma crashes (wallpaper and panel disappears, 'plasmashell' process is not listed in ksysguard).
