[igraph] Possible bug transitivity for barabasi.game

[Anindya Ghosh]

I am calculating the clustering coefficients of networks generated using the following code

n <- 10000

g <- barabasi.game(n)

transitivity(g)

I always get transitivity as 0 irrespective of the value of n. Is this is a bug? 

According to the literature it should not be 0. Any help will be appreciated.
