Instead of using QStyleOption::initFrom, let's use QGraphicsWidget::initStyleOption, which is made for exactly the purpose of KItemListWidget. This is especially important since, according to the docs of QGraphicsItem::paint "The widget argument is optional. [...] For cached painting, widget is always 0.". Even though currently no code in dolphin does cached painting, for the sake of modularity one should not rely on widget to be non-null. Using QStyleOption::initFrom does assume that, though. In fact, GammaRay asks the items to do cached painting when attaching it to the application, causing it to crash.
