关于glade的一个问题,请指教

CHENSG

用glade编写界面,用C语言写程序,编写一个聊天室程序,在运行程序时,出现了错误,界面关闭,向这里的高手请教.
错误信息如下:
Xlib: unexpected async reply (sequence 0x105e)!
The program 'client' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAtom (invalid Atom parameter)'.
  (Details: serial 7791 error_code 5 request_code 18 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)
