Hi,
I'm trying to compile a program that uses PyQt4 with the multiprocessing.BaseManager. So the program is windowed and all works fine, expecting when I quit/close the application I get following error:

The error not influence the running code, but is only annoying and for a user it seems like something went wrong.When I running in normal python console or compiled with console all is normal and no error is shown. I also don't know how correctly debug such a error. I'm sorry!

Here is the little and simplified code snipped which is already not working:

import datetime

import multiprocessing
from multiprocessing import Manager
from multiprocessing.managers import BaseManager

import time
import sys
from PyQt4 import QtGui, QtCore

if __name__ == '__main__':
    multiprocessing.freeze_support()
    app = QtGui.QApplication(sys.argv)

    window = QtGui.QWidget()
    window.setFixedHeight(300)
    window.setFixedWidth(400)
    window.setWindowTitle("Demo App")

    manager = BaseManager()
    manager.start()

    sys.exit(app.exec_())

Compile as followed:

pyinstaller -D -w demo.py

I tried it on Windows Server 2012 R2 and Windows 7, in 64bit and 32bit Python 3.4.4 and the newest PyInstaller. Pip and all components are up to date. I tried all possibilities, shutdown manager on exit and so on, nothing helped.

It seems to me that it is a bug. I would be really great if that gets fixed.

Thanks for any help.
