Description willronsonkde 2017-01-29 03:19:27 UTC
Application: systemsettings5 (5.8.5)

Qt Version: 5.8.0
Frameworks Version: 5.30.0
Operating System: Linux 4.9.6-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Open System Settings -> Desktop Behavior -> Screen Locking then go back with All Settings button.  Only Screen Locking tab causes crash.  Does not change if you switch to another tab before going back.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
