Title:
  creating and immediately destroying an SDL window crashes gnome-shell
  with signal 5

Status in gnome-shell package in Ubuntu:
  New

Bug description:
  Running this Python script (requires python-sdl2 or python3-sdl2)
  immediately crashes gnome-shell.

  import sdl2
  sdl2.SDL_Init(0)
  window = sdl2.SDL_CreateWindow(
      b'Hello, world!',
      sdl2.SDL_WINDOWPOS_UNDEFINED, sdl2.SDL_WINDOWPOS_UNDEFINED,
      640, 480, 0)
  sdl2.SDL_DestroyWindow(window)
  sdl2.SDL_Quit()

  If gnome-shell was run from a terminal, its console output is

  (gnome-shell:10965): Gdk-ERROR **: The program 'gnome-shell' received an X 
Window System error.
  This probably reflects a bug in the program.
  The error was 'BadWindow (invalid Window parameter)'.
    (Details: serial 3567 error_code 3 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.)
