Description Chris Guiver 2019-11-03 01:30:47 UTC 
Application: systemsettings5 (5.16.5)

Qt Version: 5.12.5
Frameworks Version: 5.61.0
Operating System: Linux 5.3.7-301.fc31.x86_64 x86_64
Distribution: "Fedora release 31 (Thirty One)"

-- Information about the crash:
- What I was doing when the application crashed:

I wasn't trying to change a setting, I was looking for the setting I want to change. I want to move close/minimize/maximize buttons top-right of window to top-left, so was going thru settings looking for where that is, so I could change it. I was entering each menu item from top down and moving to next quickly when I didn't find what I wanted...

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
