ubuntu 13.04, Qt4, Python 2.7

В дизайнере создаю форму, через pyuic4 получаю python код (пример моей проблемы), дописываю функцию openFile :

# -*- coding: utf-8 -*-
# Form implementation generated from reading ui file 'test.ui'
#
# Created: Sat May 25 22:56:45 2013
#      by: PyQt4 UI code generator 4.10

    _fromUtf8 = QtCore.QString.fromUtf8

        return s

    _encoding = QtGui.QApplication.UnicodeUTF8
    def _translate(context, text, disambig):
        return QtGui.QApplication.translate(context, text, disambig, _encoding)

        return QtGui.QApplication.translate(context, text, disambig)

        self.centralwidget.setObjectName(_fromUtf8("centralwidget"))
        self.pushButton = QtGui.QPushButton(self.centralwidget)
        self.pushButton.setGeometry(QtCore.QRect(140, 90, 90, 23))
        self.pushButton.setObjectName(_fromUtf8("pushButton"))
        self.label = QtGui.QLabel(self.centralwidget)
        self.label.setGeometry(QtCore.QRect(20, 40, 361, 20))
        self.label.setFrameShape(QtGui.QFrame.Box)
        self.label.setObjectName(_fromUtf8("label"))
        MainWindow.setCentralWidget(self.centralwidget)
        self.retranslateUi(MainWindow)
        QtCore.QObject.connect(self.pushButton, QtCore.SIGNAL(_fromUtf8("clicked()")), self.openFile())
        QtCore.QMetaObject.connectSlotsByName(MainWindow)
    def retranslateUi(self, MainWindow):
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow", None))
        self.pushButton.setText(_translate("MainWindow", "PushButton", None))
        self.label.setText(_translate("MainWindow", "TextLabel", None))
    
    def openFile(self):
        filename = QtGui.QFileDialog.getOpenFileName(self, 'Open File', os.getenv('HOME'))
        self.label.setText(_translate("MainWindow", filename, None))
       #print filename
if __name__ == "__main__":
    import sys
    app = QtGui.QApplication(sys.argv)
    MainWindow = QtGui.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

никакой смысловой нагрузки функция не несет

    def openFile(self):
        filename = QtGui.QFileDialog.getOpenFileName(self, 'Open File', os.getenv('HOME'))
        print filename

выдает ошибку :

me@Victoria:~/Documents$ python test.py
Traceback (most recent call last):
File “test.py”, line 60, in <module>
ui.setupUi(MainWindow)
File “test.py”, line 43, in setupUi
QtCore.QObject.connect(self.pushButton, QtCore.SIGNAL(_fromUtf8(“clicked()”)), self.openFile())
File “test.py”, line 52, in openFile
filename = QtGui.QFileDialog.getOpenFileName(self, ‘Open File’, os.getenv('HOME'))
TypeError: QFileDialog.getOpenFileName(QWidget parent=None, QString caption=QString(), QString directory=QString(), QString filter=QString(), QString selectedFilter=None, QFileDialog.Options options=0): argument 1 has unexpected type ‘Ui_MainWindow’

Подскажите в чем ошибка, я понимаю, что Ui_MainWindow имеет не тот ти что надо, но как исправить ? Если функции getOpenFileName вместо self передать None, диалог открывается и всё работает.
