Minimal testcase
This test creates a main window with a single QQuickWidget.
Via setContextProperty the pointer to the MainWindow instance is stored.
If at Qml side a property of this instance is accessed we get this
crash in the destructor.
(An exmple gdb run on my machine is included.)
please provide that test case to the Qt developers through their bugtracker. Here it won't help. Thank you for the feedback. I created https://bugreports.qt.io/browse/QTBUG-57714.

Unfortunately we need to do it for every single module that crashes. It seems that whilst the only KCMs that crash are all QML KCMs, it's not the case that all QML KCMs crash. Currently I know of KWin decoration and screen locker. Can people please list any other module that may need fixing, and I'll try and write a patch. 1) part 1 https://phabricator.kde.org/D4533 *** Bug 376151 has been marked as a duplicate of this bug. *** Git commit 29179f115c81ff7128bb5430cb27ef7b65f46b33 by David Edmundson.

Avoid a crash on Kwin decoration KCM teardown Summary: As described in https://bugreports.qt.io/browse/QTBUG-57714 exposing a QWidget as a context item to QtQuick can crash. Especially as the engine's context property gets deleted whilst deleting the parent item. This patch reworks the code so that the models are exposed to QML directly rather than going through a QWidget. Test Plan: Pressing back whilst in the decoration KCM used to crash every time, now it doesn't. I still have the buttons.

Colors crash backtrace
Add "Colors" to the list.
@Tony: Thanks, you seem to be running a very recent git snapshot, right? I did a fix for KHintsSettings (in plasma integration) so changing the color scheme at runtime would properly repainting QML parts. This exposed a bug in KCModuleQml which would unconditionally update the colors even though the QML container window was already gone. I bet you had a QML-based KCM opened (most likely the Desktop Effects one) before you changed the colors? This is fixed in kcmutils: https://cgit.kde.org/kcmutils.git/commit/ Just as a information. Attached to the upstream bug QTBUG-57714 is a patch against qtdeclarative-opensource-src-5.7.1 to attempt to fix the problem there. In my short tests it worked as expected. *** Bug 376392 has been marked as a duplicate of this bug. *** *** Bug 376358 has been marked as a duplicate of this bug. *** *** Bug 376323 has been marked as a duplicate of this bug. *** *** Bug 376208 has been marked as a duplicate of this bug. *** *** Bug 375629 has been marked as a duplicate of this bug. *** *** Bug 374941 has been marked as a duplicate of this bug. *** *** Bug 374851 has been marked as a duplicate of this bug. *** *** Bug 374042 has been marked as a duplicate of this bug. *** have the same with TW 2017.02.11 Created attachment 104005 [details]
