Model Builder (graphical ODE simulation) (PyMB.py) crashes

[ernesto]

Program crashes on start up because it fails to load mathplotlib.numerix. On
http://http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=684681 can be found the same bug
as reported by Jakub Wilk <jwilk-AT-debian.org> (Sun, 12 Aug 2012 22:42:22 +0200) (warnings
from Wilk report matches exactly as repoted below).

As responde by supplier of updated model-builder package Varun Hiremath <varun-AT-debian.org>
(Fri, 17 Aug 2012 00:32:40 +0000) this bug should as been corrected; however, as can be seen
below, the same bug is still lived.

Final info: we downloaded the package from ftp.debian.org and intalled instead of supplied by Canonical
and there in no diference, package behave the same.

$ lsb_release -rd
