Description Carlos Henrique Merces Moreira 2017-01-04 01:47:10 UTC

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".
