Application: plasmashell (5.8.5) Qt Version: 5.7.1 Frameworks Version: 5.29.0 Operating System: Linux 4.9.0-1-MANJARO x86_64 Distribution: "Manjaro Linux" -- Information about the crash: - What I was doing when the application crashed: I finished my day work, and tried to close multiple Okular instances that were opened, as soon as I started doing this the system screen blinked and the task bar dissapeared, but after few seconds later everything is back to normal again. - Unusual behavior I noticed: The taskbar dissapeared, sometimes this bug happens in other ocassions and I'm unable to open other apps, so I need to reboot my system, but in this particular case the plasma restarted automatically and I was able to use the system normally after this bug happened. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".
