cannot concatenate 'str' and 'int' objects in pydot.py

[wiso]

It's the first time I'm using pydot, I've copied the example

import pydot
edges=[(1,2), (1,3), (1,4), (3,4)]
g=pydot.graph_from_edges(edges)

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "build/bdist.linux-x86_64/egg/pydot.py", line 237, in
graph_from_edges
TypeError: cannot concatenate 'str' and 'int' objects

I'm using pydot 1.0.2 and python 2.6

thanks
