For debug builds it's exiting at 
Q_ASSERT(data && data->propertyCache);

in QQmlBinding::getPropertyData

Comment 4 Christoph Feck 2017-06-27 13:22:01 UTC 
Could be caused by commit for https://bugreports.qt.io/browse/QTBUG-57633 because it adds code to clear data->propertyCrash.
Comment 5 Christoph Feck 2017-06-27 13:35:35 UTC 
LOL, of course I mean data->propertyCache. Too many bug triaging...
Comment 6 David Edmundson 2017-06-27 19:29:36 UTC 
Interesting notes:

I could reproduce the version of this crash in analog-clock, I put in some mad GDB, and found it was updating:

Plasmoid.toolTipMainText: ...
The crash in network manager show connectionTooltipIconChanged, 

which is used in a binding on Plasmoid.toolTip

That's too much of a coincidence.
Comment 7 David Edmundson 2017-06-27 20:38:19 UTC 
That matches your idea about that link:

The AppletConfig does create a new QQmlEngine, for a reason that I don't remember.
AppletInterface (which is "Plasmoid" from QML terms) is shared in both.
Comment 8 Kai Uwe Broulik 2017-06-27 20:42:37 UTC 
I think it's so the config dialog can use desktop style QtQuick Controls whereas the rest of Plasma does not.
Comment 9 David Edmundson 2017-06-28 00:35:11 UTC 
Confirmed, it's this change:

https://codereview.qt-project.org/#/c/192037/3/src/qml/jsruntime/qv4qobjectwrapper.cpp

remove those two and we don't crash.

Debug shows it's the same QQmlData between the two engines; which I think is right; but it either shouldn't be setting the prop cache when one gets deleted, or it should be re-instantiating it (changing QQmlData::get(*m_target, false to true) where it crashes.

I'll make a reproducible simple Qt case tomorrow.
Comment 10 David Edmundson 2017-06-28 11:22:44 UTC 
To answer the ineviatible question: Can we make ConfigView use a shared engine to work round it.

The theme thing isn't really an issue. 

We can't easily change and keep compatibility. 

Changing the base class of ConfigView is an API break, and just making a new context internally would break  existing use of ConfigView::rootContext() which PanelConfig uses.

I don't see a simple solution for a workaround.

Same situation here. But now it has gotten worse. When I lock the session, after a long time when accessing again, I present the same problem, the panels, the wallpaper, have disappeared. I have to run plasmashell in KRunner. This is my log:

Comment 63 Edward Kigwana 2017-10-25 03:18:51 UTC 
I've noticed a lot duplicates, however, according to https://bugreports.qt.io/browse/QTBUG-61681 is fixed for Qt 5.9.2 but I still hit this bug. Is there a patch waiting for Qt 5.9.2 in KDE?
