Backport PR : Fixed minor typo causing AttributeError to be thrown. I'm not sure how I caused the error to be thrown and couldn't reproduce it with the same call again, nevertheless I think the fix is correct. ```python In [21]: rc.shutdown(hub=True) Traceback (most recent call last): File "<ipython-input-21-977a05a15f31>", line 1, in <module> rc.shutdown(hub=True) File "<string>", line 2, in shutdown File "c:\dev\code\ipython\IPython\parallel\client\client.py", line 69, in spin_first self.spin() File "c:\dev\code\ipython\IPython\parallel\client\client.py", line 1005, in spin self._flush_notifications() File "c:\dev\code\ipython\IPython\parallel\client\client.py", line 800, in _flush_notifications raise Exception("Unhandled message type: %s"%msg.msg_type) AttributeError: 'dict' object has no attribute 'msg_type' ```
