cluster_fast_greedy() with argument 'modularity = FALSE' crashes R session

Hi,

for me changing the modularity argument of the cluster_fast_greedy() function crashes the R session. Following example reproduces this. Also happens with undirected weighted networks.

A <- matrix(sample(c(0,1), 100, replace = TRUE), 10, 10)
diag(A) <- 0
g <- graph_from_adjacency_matrix(A, mode = "undirected")

this works:
cluster_fast_greedy(g)

this then crashes the R session:
cluster_fast_greedy(g, modularity = FALSE)

Spoke too soon; the bug is not R-specific. Refer to igraph/igraph#836 instead.
