Application: plasmashell (5.5.3) Qt Version: 5.5.1 Operating System: Linux 4.3.3-303.fc23.x86_64 x86_64 Distribution: "Fedora release 23 (Twenty Three)" -- Information about the crash: - What I was doing when the application crashed: Booted my laptop with an external screen as the primary display - Unusual behavior I noticed: Start the control panel and switch off the laptop screen -> apply -> switch on the laptop screen -> apply causes the crash and after a restart everything is fine. The crash can be reproduced sometimes. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
