Strange Queue error

Sounds like you set the qlist variable like so:

    qlist = Queue.Queue

instead of 

    qlist = Queue.Queue()

Note the difference:

    >>> import Queue
    >>> qlist = Queue.Queue()
    >>> import time
    >>> qlist.put((time.sleep, 5))
    >>> qlist = Queue.Queue
    >>> qlist.put((time.sleep, 5))
    Traceback (most recent call last):
      File "<stdin>", line 1, in ?
    TypeError: unbound method put() must be called with Queue instance as first argument (got tuple instance instead)
