Python freezes when PyQT4 mixes with BaseHTTPServer - python-2.7

Question

I have an error in my Python code, I'm new to Python, and I'm also new to PyQT. What I'm trying to do is build a basic http proxy server with a GUI. I've done it in the console, but when I tried to implement a GUI, I'm getting an error.
Here is my code, any help is appreciated.
import BaseHTTPServer, SocketServer,sys
from PyQt4 import QtCore, QtGui
from Ui_MiniGui import Ui_MainWindow
class ThreadingHTTPServer(SocketServer.ThreadingMixIn, BaseHTTPServer.HTTPServer):
pass
class webServer(QtCore.QThread):
log = QtCore.pyqtSignal(object)
def __init__(self, parent = None):
QtCore.QThread.__init__(self, parent)
def run(self):
self.log.emit("Listening On Port 1805")
Handler = BaseHTTPServer.BaseHTTPRequestHandler
def do_METHOD(self):
method = self.command
#I got some trouble here, how can i emit the signal back to the log?
#self.log.emit(method) not work, python not crash
#webServer.log.emit(method) not work, python not crash
#below one not work and python crashes immediately
webServer().log.emit(method)
Handler.do_GET = do_METHOD
self.httpd = ThreadingHTTPServer(("", 1805), Handler)
self.httpd.serve_forever()
class Form(QtGui.QMainWindow):
def __init__(self, parent=None):
QtGui.QWidget.__init__(self, parent)
self.ui = Ui_MainWindow()
self.ui.setupUi(self)
self.server = webServer()
self.server.log.connect(self.write_to_textEdit)
self.server.start()
def write_to_textEdit(self, data):
print data
self.ui.textEdit.setText(data)
if __name__ == "__main__":
app = QtGui.QApplication(sys.argv)
myapp = Form()
myapp.show()
sys.exit(app.exec_())

In this line
webServer().log.emit(method)
You create a new webserver instance and emit it's log signal. As this is a new object, this signal hasn't been connected to anything, so it's doing nothing.
To emit the signal on the right object, you could do the following:
def run(self):
...
server = self
def do_METHOD(self):
...
server.log.emit(self)
