I noticed that my old code stop working correctly when I had upgraded to Qt 5.4.1. Part of code is below:
TargetItemListWidget::TargetItemListWidget(QWidget * parent) : QListWidget(parent)
{
	setMouseTracking(false);
	setDragEnabled(false);
	setDragDropMode(QAbstractItemView::InternalMove);
	setDefaultDropAction(Qt::MoveAction);
	setSelectionMode(QAbstractItemView::ExtendedSelection);
	setSelectionBehavior(QAbstractItemView::SelectRows);
}
void TargetItemListWidget::dropEvent(QDropEvent * event)
{
	QListWidget::dropEvent(event);
	emit dropItem();
}
After drag'n'drop QListWidgetItem is deleted. So now I temporarily solved this problem by adding clearSelection() after emit dropItem()
