[New-bugs-announce] [issue6639] turtle: _tkinter.TclError: invalid command name ".10170160"

[Sridhar Ratnakumar]

New submission from Sridhar Ratnakumar <sridharr at activestate.com>:

I tried the following turtle program; it was taking some time to 
draw .. so I pressed C-c after which I saw the exception traceback.

> cat play.py 
from turtle import *

def f(length, depth):
   if depth == 0:
     forward(length)
   else:
     f(length/3, depth-1)
     right(60)
     f(length/3, depth-1)
     left(120)
     f(length/3, depth-1)
     right(60)
     f(length/3, depth-1)

f(500, 4)

> python play.py
