error with window.close() in a on_mouse_motion listener

run:

import pyglet

window = pyglet.window.Window()
label = pyglet.text.Label('Hello, world', 
                          font_name='Times New Roman', 
                          font_size=36,
                          x=window.width//2, y=window.height//2,
                          anchor_x='center', anchor_y='center')

@window.event
def on_mouse_motion(x, y, dx, dy):
    window.close()

@window.event
def on_draw():
    window.clear()
    label.draw()

pyglet.app.run()

if your mouse is ontop of the window when it appears the output is spammed
with stack traces. i was unable to copy the output, but the error message
says glDeleteBuffers is called before the GL context is created.
