Bug ID: 376012
Summary: System Settings>Window decoration crashes on close
Product: systemsettings
Version: unspecified
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: jodr...@live.com
Target Milestone: ---
Application: systemsettings5 (5.9.90)
Qt Version: 5.7.1
Frameworks Version: 5.31.0
Operating System: Linux 4.9.8-040908-lowlatency x86_64

-- Information about the crash:
- What I was doing when the application crashed:
I changed the dafault one for any other one, hit apply then close the window.
This happens everytime, even if you don't make any changes. Just open System
Settings>Window decoration and close the window.
The crash can be reproduced sometimes.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
