[igraph] community_fastgreedy() requires integers as edge weights?

[Kurt J]

Hi All,

Using the fastgreedy community detection with edge weights i get the following error:

> Traceback (most recent call last):
>   File "<stdin>", line 1, in <module>
>   File "graphmeasures.py", line 226, in getCom
>     vcG = G.community_leading_eigenvector()
>   File "build/bdist.macosx-10.3-fat/egg/igraph/__init__.py", line 437, in community_fastgreedy
> TypeError: sequence elements must be integers

If i understand the algorithm, it should be quite happy with floats.  Am I wrong? Is this a bug?
