Thanks for the bug report. Looks like the crash happens in accessibility-related code. Do you use any accessibility-related tools (like KWin's zoom plugin)? It seems that the crashing line in "QRect KItemListViewAccessible::rect(int child) const" is const QPoint origin = view()->scene()->views()[0]->mapToGlobal(QPoint(0, 0)); @Frederik: I did not know if any of the "Amandeep Singh" that Bugzilla knows is the right one.
