Description Debashis Dash 2017-04-03 23:44:19 UTC

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".
