Description
Probably since https://codereview.qt-project.org/c/qt/qtbase/+/636265 by mmutz and richard QDockWidget sends visibilityChanged signal on destruction.
This can lead to crashes in user code when a main widget is supposed to be reacting to changed visibility and e.g. hide/show/modify other data members of same widget.
This is seen in Okular auto tests as part of the tests for Qt Next.
There is also a quite small example in
