    Description

      A layout item for a child widget is not deleted if the layout was deactivated before the child widget is deleted. The ChildRemoved event is ignored in this case due an early return in QLayout::widgetEvent(QEvent *e).

      The application crashes the next time the layout is activated and a method like totalMinimumSize() ist called because the orphaned element refers to a now invalid widget.

      The bug also exists in 5.15.2 and later.
