Do not try to smooth-scroll past the end of the view
KItemListSmoothScroller::scrollTo(qreal position) did not check if 'position' is a valid value. Even if the view is scrolled to the bottom already, it tried to scroll further and activated "smooth scrolling" when the mouse wheel is used. Because it never got out of the "smooth scrolling" state then, it got confused when changing the directory, and restoring the correct scroll offset could fail.
