这似乎是由于在传递QTreeWidgetItem作为第一个参数时，QTreeWidgetItemIterator中的PySide错误引起的。当QTreeWidget作为第一个参数传递时，问题就消失了。使用等效的PyQt4代码不会出现此错误。在

可以通过修改selectMirroredItems中的以下行来修复示例代码：

    # TreeWidgetItems = QtGui.QTreeWidgetItemIterator( topItems[0] )
    TreeWidgetItems = QtGui.QTreeWidgetItemIterator(widget)

似乎简单地迭代QTreeWidgetItemIterator就足以导致segfault（尽管我没有费心创建一个最小的测试用例）。在

PySide错误可以报告here。在
