In matplotlib/legend.py, on line 182, try replacing 

            elif isinstance(handle, Rectangle):

with 

            elif isinstance(handle, Patch):

and try again.  If it fails, please send in an example script that
exposes the problem, but let me know in any case.  Note this solution
will still draw a little rectangle in the legend rather than a
miniature polygon the same shape as the fill one, but it will
otherwise have the same properties (eg facecolor).  What does matlab do?
