Your backtrace is a different issue Vishnu. See bug 412915.
Comment 7 David Edmundson 2019-10-16 21:18:03 UTC 
I've found what's going wrong.

It's in KCModuleLoader when it creates the KQuickAddons::ConfigModule then creates the wrapper.

The wrapper is managed by a parent, but the KQuickAddons::ConfigModule is not.

Upon deletion the KCM is in an unknown weird state, which isn't worth debugging till this is solved.
Comment 8 David Edmundson 2019-10-17 11:59:55 UTC 
Git commit aea58fcca35984fff73e1c77dc2edb346da4e69b by David Edmundson.
Committed on 17/10/2019 at 09:09.
Pushed by davidedmundson into branch 'master'.

Fix memory leak of KQuickAddons::ConfigModule objects

Summary:
When we create a KQuickAddons::ConfigModule  in the factory we didn't
set a parent. It is passed to the wrapper KCModuleQML, and even though
the wrapper is memory manager the ConfigModule object itself was not.

This lead to another crash as the KAboutData is deleted twice, which was
fixed with an explicit copy

Test Plan:
qDebug inside the colours KCM destructor
It now appears when changing tabs

New crash information added by DrKonqi

systemsettings5 (5.17.0) using Qt 5.13.1

- What I was doing when the application crashed: 1. Opened System Settings
2. Selected Gamma (Compositor also crashes)
Crashes straight away, every time

- Unusual behavior I noticed: Happened only after the recent KDE update, and I'm seeing crashes for my browsers (they don't open at all, and valgrind shows ml/module undefined) as well, not sure how relevant this info is.
