ladybird/Ladybird/Qt/BrowserWindow.cpp
Timothy Flynn 4653733a0d Ladybird/Qt: Do not "share" ownership of Qt objects 
When a QObject subclass (widgets, etc.) are provided a parent, then
ownership of that object is passed to the parent. Similarly, objects
added to a QLayout are owned by the layout.

Thus, do not store these objects in an OwnPtr.
