[O] are babel python sessions and inlined images incompatible?

[Rodrigo Amestica]

Hello,

if I use this block

#+BEGIN_SRC python :results file
from pylab import *
plot(rand(10))
savefig('images/test.png')
return 'images/test.png'
#+END_SRC 

then the RESULTS block shows me an inlined version of the plot.

If now I switch to this block

#+BEGIN_SRC python :session test :results file
from pylab import *
plot(rand(10))
savefig('images/test.png')
return 'images/test.png'
#+END_SRC 

then the RESULTS block does not show the inlined plot but this

| <matplotlib.lines.Line2D | object | at | 0x35c0650> |

Using a session is kind of mandatory for me because I need several blocks to
share variables.

Is there something evidently wrong with my approach?

thanks,
 Rodrigo
