Fails to launch remotely with X11 forwarding

[tedgin]

Describe the bug
When I'm remotely connected to my Linux desktop, RedNotebook won't launch from the command line. Instead it exits with status code 133.

To Reproduce

1. Connect to a remote host with X11 forwarding enabled (ssh -X remote.host.net).
2. Attempt to launch RedNotebook (rednotebook).

Expected behavior
I expect the RedNotebook GUI to open on my local computer.

(rednotebook:479583): Gdk-ERROR **: 15:48:31.151: The program 'rednotebook' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or no such operation)'.
  (Details: serial 185 error_code 1 request_code 154 (unknown) minor_code 1)
  (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 GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

Versions:

• RedNotebook version 2.31
• Local and remote hosts are running Ubuntu 22.04.

Thanks for the report! Do other Python+GTK work remotely, such as Meld?
