[igraph] community_fastgreedy: Segmentation fault error

[Simone Caschili]

Hello igraphers,

I'm implementing a community detection analysis in a network of about 7000 edges and 400 nodes using the Pyhton version of Igraph. 

When I use the function "community_fastgreedy" I get the message "Segmentation fault". 

I have run the same function with a small network of about 10 nodes and 10 edges and it works perfectly. 

Any suggestion to solve this issue? 

Regards,
Simon C.
