python Gtk应用失败，并显示此错误xcb xlib线程序列失败

问题描述

我有一个pyGObject应用，然后运行它。一切正常，直到单击按钮的信号我需要运行def。它有一个很长的循环，我用

def on_launch_btn_clicked(self,button): 
    _thread.start_new_thread(launch,["thread"])


def launch(thread):
    lines_list = open("../line.txt").split()
    for line in lines_list:
        select = machinestate.objects.get(id=1)
        if not select.pause:
            #my process
        else:
            def pause_lcd()
            return "pause" #it for come out of def and close thread but I don't know it close that or not

此循环在另一个.py文件中

功能就像一个咒语，接下来我有一个暂停按钮，它将数据库暂停字段更改为True，并在每次迭代检查数据库时循环查看更改。当看到暂停为True时，它将运行

def pause_lcd():
    app = app_list[0]
    app.pause_action()  

我在此def中运行Gtk应用

app_list = list()
def main(thread):
    app = GUI()
    app_list.append(app)
    Gdk.threads_init()
    Gtk.main()

在我的GUI类中，我有pause_action方法

def pause_action(self):
    self.pause_btn.set_sensitive(True)
    self.pause_btn.hide()
    self.resume_btn.show()

当我单击暂停按钮一段时间后，出现此错误

[xcb] Unknown sequence number while processing queen
[xcb] Most likely this is a mulity-threaded client and XinitThreads has not been called
[xcb] Aborting,sorry about that
pyhton: ../../src/xcb_io.c:263 poll_for_event: Assertion '!xcb_xlib_threads_sequence_lost failed.

我有一堆线程，例如机器信息，时钟，机器温度和...

我做错了什么？

PS：此应用程序在Django项目中运行，我在其中使用Django模型，它是Django的应用程序，但它运行的是Gtk应用程序

解决方法

我怀疑 XCB 或 X11 服务器有问题（错误）。我从特定 X 服务器上的不同应用程序收到相同的错误消息（通过 ssh 使用 X11）。

emacs 的错误信息：

[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting,sorry about that.
