looks most likely like a bug in Qt 4.6's QGraphicsView (painting something that is already removed from the scene); though it could also be a bug in kdelibs 4.4.x's KIconLoader, though looking at the code path in the backtrace i can't see how. almost certainly one of the item cache bugs from 4.6 ...
