Gdk-ERROR

[Jeffrey Elkner]

Running the following little program from GASP Lessons Sheet 2:

from gasp import *

begin_graphics()

for r in range(100, 141, 10):
    Circle((300, 200), r)

update_when('key_pressed')
end_graphics()

Resulted in the following:

$ python3 pretty_picture.py
[DBG]: On Windows

(pretty_picture.py:23363): Gdk-ERROR **: 13:21:55.280: The program 'pretty_picture.py' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAccess (attempt to access private resource denied)'.
  (Details: serial 202 error_code 10 request_code 130 (MIT-SHM) 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.)
