Wxpython script gives "TypeError: 'in <string>' requires string as left operand, not QString"

Question

this simple wxpytohn script gives the following error, what is wrong? The error message doesnt give which line the error occurs in script:

Traceback (most recent call last):
  File "c:\Python27\lib\site-packages\spyderlib\plugins\externalconsole.py", line 721, in run_script_in_current_shell
    "and try again.") % osp.basename(filename), QMessageBox.Ok)
  File "c:\Python27\lib\ntpath.py", line 198, in basename
    return split(p)[1]
  File "c:\Python27\lib\ntpath.py", line 173, in split
    while i and p[i-1] not in '/\\':
TypeError: 'in <string>' requires string as left operand, not QString

This is the script:

import wx
import os


def getParentFolder():
    moduleFile = __file__
    moduleDir = os.path.split(os.path.abspath(moduleFile))[0]
    programFolder = os.path.abspath(moduleDir)
    parentFolder = os.path.abspath(os.path.join(programFolder, os.pardir))
    return programFolder, parentFolder

class MainWindow(wx.Frame):

    def __init__(self, title):
        wx.Frame.__init__(self, None, title=title, pos=(150,150), size=(1200,900))
        #self.Bind(wx.EVT_CLOSE, self.closeWindow)
        self.SetIcon(wx.Icon("plane.ico", wx.BITMAP_TYPE_ICO))
        self.Center()

        icons_folder = getParentFolder()[1] 

        menubar = wx.MenuBar()
        scenario_menu = wx.Menu()
        database_menu= wx.Menu()
        settings_menu = wx.Menu()


        open_scenario = wx.MenuItem(scenario_menu, 101, '&Open\tCtrl+O', 'Open an existing scenario')
        open_scenario.SetIcon((wx.Icon(icons_folder+"\\open_dir.ico", wx.BITMAP_TYPE_ICO)))
        scenario_menu.AppendItem(open_scenario)

        scenario_menu.Append(102, "&Create", "Create new scenario")
        scenario_menu.Append(103, "&Save", "Save scenario")

        menubar.Append(scenario_menu, "&File")
        menubar.Append(database_menu, "&Database")
        menubar.Append(settings_menu, "&Settings")



if __name__ == "__main__":
    app = wx.App()
    frame = MainWindow("CrewOpt")
    frame.Show()
    app.MainLoop()

There is a spyderlib issue for this here. Apparently it's closed, so maybe try updating your libraries and see if it's still a problem.
