turtle, ipython, and pylab don't mix

[Brian Blais]

Hello,

I am noticing a hard crash of the ipython interpreter, with the pylab  
option, with the turtle module.  I am on Win XP, Enthought Edition  
6.0.0 which uses Python 2.6.  I can't reproduce it without the pylab  
option, nor on the Mac (with an earlier Enthought Edition).  The  
crash happens only when I try to move the turtle window, after it has  
drawn.  The following commands are enough to give the resulting error.

In [1]: from turtle import *

In [2]: pendown()

In [3]: forward(10)

In [4]: Fatal Python error: PyEval_RestoreThread: NULL tstate

This application has requested the Runtime to terminate it in an  
unusual way.
Please contact the application's support team for more information.


Any ideas?  Of course, I'll use it without the pylab option, but that  
means that there are two icons I need instead of one.  Minor  
inconvenience for me, but a bit more of a pain for my students.


		thanks,

			Brian Blais
