title: PyQt4: How to load compiled ui-files correctly?
body: <p>I created a Qt resource file with all my ui files inside of it, I compiled that with pyrcc4 command-line in a python file, and then I loaded the ui files using loadUi. Here an example:</p>
  
  <pre><code>#!/usr/bin/env python
  #-*- coding:utf-8 -*-
  
  import os
  import sys
  
  from PyQt4.QtCore import Qt, QFile
  from PyQt4.uic import loadUi
  from PyQt4.QtGui import QDialog
  
  from xarphus.gui import ui_rc
  # I import the compiled qt resource file named ui_rc
  
  BASE_PATH = os.path.dirname(os.path.abspath(__file__))
  #UI_PATH = os.path.join(BASE_PATH, 'gui', 'create_user.ui')
  UI_PATH = QFile(":/ui_file/create_user.ui")
  # I want to load those compiled ui files, 
  # so I just create QFile.
  
  class CreateUser_Window(QDialog):
      def __init__(self, parent):
  
          QDialog.__init__(self, parent)
  
          # I open the created QFile
          UI_PATH.open(QFile.ReadOnly)
          # I read the QFile and load the ui file
          self.ui_create_user = loadUi(UI_PATH, self)
          # After then I close it
          UI_PATH.close()
  </code></pre>
  
  <p>Well its works fine, but I have a problem. When I open the GUI-window once, everything works fine. After closing the window I try to open the same GUI-window again, I get ja long traceback.</p>
