Application: plasmashell (5.10.5) Qt Version: 5.9.1 Frameworks Version: 5.38.0 Operating System: Linux 4.13.4-1-default x86_64 Distribution: "openSUSE Tumbleweed" -- Information about the crash: - What I was doing when the application crashed: Before opening laptop I connected the additional extra screen/monitor. Opened laptop to resume from standby I noticed the screen config was messed up as the laptop screen was moved over the external screen in Configure Desktop/Monitor. I had to move the laptop screen back to be next to the external screen and applied config. Up to this point Plasma was in a funky state where no taskbar was present. Only after applying the monitor config for the screens to be next to one another, then did plasma restart and the taskbar re-appeared. The crash can be reproduced sometimes. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

No new reports in a year and a half and the multi-monitor infrastructure has been re-done; assuming once again that it's been fixed.
