OSError: [Errno 22] Invalid argument in python3 socket [closed]

Question

I have a problem with socket programming in Python 3. I get an exception that is not making the program crash, but is just shown in terminal.

Here is my code:

from PyQt4 import QtCore, QtGui
from imigui import Ui_MainWindow

class imiserv(QtGui.QMainWindow):

    send_msg = pyqtSignal('QString', 'QString')

    def __init__(self, parent=None):
        QtGui.QWidget.__init__(self, parent)
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
        self.ui.Sport_lineEdit.setMaxLength(5)
        self.ui.Sconnect_pushButton.clicked.connect(self.serv)

        self.send_msg.connect(self.write_msg)

    def write_msg(self, lbl_msg= None, txt_msg= None):
        if lbl_msg:
            self.ui.C_label.setText(lbl_msg)
        if txt_msg:
            self.ui.Clog_textEdit.setText(txt_msg)

    def serv(self):
        MY_LOCK = threading.Lock()
        class CountT(threading.Thread):
            def __init__(self, parent):
                threading.Thread.__init__(self)
                self._parent= parent

            def run(self):
                MY_LOCK.acquire()
                self._parent.send_msg.emit("Waiting connections","")
                while True:
                    cliconn, (addr, remoport)= self._parent.clis.accept()
                    clirecmsg= str(cliconn.recv(1024)
                    self._parent.send_msg.emit("{0}:{1} is connected.".format(addr, remoport), "{0}:{1}".format(addr, remoport)
                    cliconn.close()

                MY_LOCK.release()

        try:
            self.clis= socket.socket(socket.AF_INET, socket.SOCK_STREAM)
            self.clis.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
            clierhost= str(self.ui.Sip_lineEdit.text())
            clierport= int(self.ui.Sport_lineEdit.text())
            self.clis.bind((clierhost, clierport))
            self.clis.listen(5)
            a= CountT(self)
            a.daemon= True
            a.start()
        except socket.error as err:
            err= str(err)
            print(err)

And here are the errors that happened decussate (this error show only in linux os):

Exception in thread Thread-1:

  File "/usr/lib/python3.3/socket.py", line 135, in accept
    fd, addr = self._accept()
OSError: [Errno 22] Invalid argument

in short: use 192.168.1.x instead of 127.0.0.1
