Application: plasmashell (5.9.4) Qt Version: 5.8.0 Frameworks Version: 5.32.0 Operating System: Linux 4.10.6-1-ARCH x86_64 Distribution (Platform): Archlinux Packages -- Information about the crash: - What I was doing when the application crashed: I had put my laptop to sleep by closing the lid. Then I docked the laptop without opening the lid. After docking, I opened the lid. The screen did not come on. Most of the times that this happens, I have to force reboot. Sometimes, when I undock, plasma crashes and the screen comes back on with the login screen (all apps still running when I login). The crash can be reproduced sometimes. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".
