Solve the following python programming problem given the following code:
def run_dev_server(application) : 
    servers = [] 
    def tracking_make_server(* args, **kwargs) : 
        srv = real_make_server (* args, ** kwargs) 
        servers.append (srv) 
        return srv 
serving.make_server = tracking_make_server 
    try : 
        t = Thread (target = serving.run_simple, args = ('localhost', 0, t)) 
        t.setDaemon (True) 
        t.start () 
        time.sleep (0.25) 
finally : 
        serving.make_server = real_make_server 
if (not servers) : 
        return (None, None) 
(server,) = servers 
    (ip, port) = server.socket.getsockname () [: 2] 
    if (':' in ip) : 
        ip = ('[%s]' % ip) 
return (server, ('%s:%d' % (ip, port))) 

    
    

    Fix the buggy line: t = Thread (target = serving.run_simple, args = ('localhost', 0, t))

#Here is Python program to fix the buggy line: t = Thread (target = serving.

t = Thread (target = serving.run_simple, args = ('localhost', 0, application))
