$ jackline-gtk 

(jackline-gtk:28469): Gdk-ERROR **: The program 'jackline-gtk' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadLength (poly request too large or internal Xlib length erro'.
  (Details: serial 186238 error_code 16 request_code 18 (core protocol) 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 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.)
Trace/breakpoint trap
133

I don't know enough about Gdk or X right now to debug this :( After this occurs, one needs to rm ~/.config/ocaml-xmpp-client/*.fifo to run jackline-gtk again.)

To debug, run with GDK_SYNCHRONIZE=1 gdb -ex "break gdk_x_error" -ex "run /usr/bin/jackline-gtk" python3
