[PyQt] Multiple Inheritance with PyQt5 on python 2

[Sebastian Eckweiler]

Hi there, 

I've just read through 
http://pyqt.sourceforge.net/Docs/PyQt5/multiinheritance.html.
I'm using a self-built PyQt5 for Python 2 on Windows - and it seems I 
can't get multiple inheritance to work:

class SomeClass(object):

    def __init__(self, attr):
        self.attr = attr

class AnotherDialog(QtWidgets.QDialog, SomeClass):

    def __init__(self, parent=None):
        #super(AnotherDialog, self).__init__(parent) # tested this was 
well
        QtWidgets.QDialog.__init__(self, parent)
        SomeClass.__init__(self, 1)


app = QtWidgets.QApplication([])
dlg = AnotherDialog()

This always results in 

TypeError: __init__() takes exactly 2 arguments (1 given)

is there a workaround for this?

Cheers,
Sebastian
