[오류 내용]

Gdk-ERROR **: The program '<PROGRAM>' received an X Window System error.

This probably reflects a bug in the program.

The error was '<SOME_ERROR>'.

 (Details: serial <AA> error_code <B> request_code <CC> minor_code <D>)

 (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.)
