The bug is fixed but I don't see the fix and I have the same problem.

When I want to display the production dashboard, my GTK client crashes (Windows and Linux).

I use these versions :

Server : 5.0.6
Client : 5.0.6
Matplotlib : 0.91.2-0ubuntu1

How to fix this bug ?

may be this helps
http://sourceforge.net/projects/matplotlib/files/matplotlib/matplotlib-0.99.1/

Thank you .

I install the last version of matplotlib, but the problem also occured.

I have an other question : Where do come the problem, openobject-client or openobject-server ?
