導航到空目錄時，我收到以下有關無效索引的控制檯垃圾郵件。我得到一個稍微不同的消息，這取決於父目錄的哪一列被雙擊以進入空目錄。雙擊名稱列後，在進入空目錄後，單擊表格中的任意位置，將導致第一組垃圾（10）。如果雙擊其他列，則會發生1 1，1 2，1 3消息。QAccessibleTable :: child：使用QTableView和QFileSystemModel的空目錄中的索引無效

我試着移動setRootIndex（）調用的位置，但它沒有幫助。還有別的東西是應該做的嗎？
此代碼似乎可以正常工作，但之前我曾經有過與此垃圾郵件相關的隨機崩潰（PyQt5 Crash with QFileSystemModel and QSortFilterProxyModel..doing something wrong?）。
import os, sys, tempfile
from PyQt5 import QtCore, QtWidgets
print(QtCore.qVersion())
class Widget(QtWidgets.QWidget):
def __init__(self, parent=None):

layout = QtWidgets.QVBoxLayout()
self.setLayout(layout)
self._view = QtWidgets.QTableView()
layout.addWidget(self._view)
self._model = QtWidgets.QFileSystemModel()
self._model.setFilter(QtCore.QDir.AllDirs | QtCore.QDir.NoDot)
self._view.setModel(self._model)
self._view.doubleClicked.connect(self._double_clicked)
# Create a temporary directory structure (tmpxyz/foo) starting at the location of this file

self.temp_dir = tempfile.TemporaryDirectory(dir=path)
print('created temporary directory', self.temp_dir.name)
foo_dir = os.path.join(self.temp_dir.name, 'foo')
os.mkdir(foo_dir)

我使用Python 3.6.1，PyQt5 == 5.8.2在Ubuntu 17.04在一個乾淨的虛擬環境中，但我得到的基礎上的Ubuntu相同的行爲與Python 3.5.3和5.7.1的PyQt 。
