Dear all,
let say I have these lines:

#+PROPERTY: session *py*
#+PROPERTY: results output

#+BEGIN_SRC python
import matplotlib.pyplot as plt
a=[1,2,3]
#+END_SRC

I execute the code block, no problem
Then I execute this:

#+BEGIN_SRC python
plt.plot(a)
#+END_SRC

boom, emacs hangs
result doesn't change if I write plt.plot(a) directly in the *Python*
buffer activated by org-babel-pop-to-session.
if I use pylab (interactive mode of matplotlib), I can see a window with
the plot, but then the *Python* shell is unresponsive, and the only thing I
can do is just killing it.

Please note that

#+BEGIN_SRC python :session none
import matplotlib.pyplot as plt
a=[1,2,3]
plt.plot(a)
plt.savefig('dummy.png')
#+END_SRC

works perfectly.

It would be wonderful for me to be able to use sessions & matplotlib...
So, thanks a lot for any suggestions!
