title: PyQt no button.clicked.connect function?
body: <p>I've got PyQt4 with a python 3.4 and there is this strange bug occurring. Whenever I try to call btn.clicked.connect(), Pycharm will throw this error:</p>
  
  <pre><code>Cannot find reference "connect" in "function".
  </code></pre>
  
  <p>So for example:</p>
  
  <pre><code>btn = QtGui.QPushButton("Quit", self)
  btn.clicked.connect(QtCore.QCoreApplication.instance().quit)
  </code></pre>
  
  <p>will throw this error. How? Do I have missing files?</p>
