Please, post the description of the problem on the bug, rather then referring to third-party links.

Luca,

It is a bug that appears when recent mpl is used with Numeric as opposed 
to numpy or numarray.  It is fixed in svn.  Your possible solutions are:

1) Use numpy or numarray instead of Numeric
2) Build mpl from svn
3) Edit axes.py as indicated in this diff chunk:

 <at>  <at>  -1217,7 +1217,7  <at>  <at> 
          ACCEPTS: len(2) sequence of floats
          """

-        if xmax is None and hasattr(xmin,'__len__'):
+        if xmax is None and iterable(xmin):
              xmin,xmax = xmin

          old_xmin,old_xmax = self.get_xlim()
 <at>  <at>  -1330,7 +1330,7  <at>  <at> 
          ACCEPTS: len(2) sequence of floats
          """

-        if ymax is None and hasattr(ymin,'__len__'):
+        if ymax is None and iterable(ymin):
              ymin,ymax = ymin

          old_ymin,old_ymax = self.get_ylim()
