Description Victor Tran 2016-07-26 06:30:23 UTC 
Application: systemsettings5 (5.7.2)

Qt Version: 5.7.0
Frameworks Version: 5.24.0
Operating System: Linux 4.6.4-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
In System Settings, under Input Devices > Touchpad, in the testing area, there is a folder that you can drag to test touchpad dragging. If you drag it onto itself, then try to start dragging it again, systemsettings crashes.

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".
