[igraph] a problem with simplify()

[Simone Gabbriellini]

Hello List,

I am trying to simplify my graph, which has loops and has no multiple edge. the 
graph has vertex and edges attributes,
Using:

g<-simplify(g, remove.multiple=FALSE, remove.loops=TRUE)

I end up with a graph that has no edge attributes... 

Vertices: 389 
Edges: 481 
Directed: TRUE 
No graph attributes.
Vertex attributes: name, starttime, endtime, nodesize, nodeshape, colorname.
No edge attributes.

Since I specified remove.multiple = FALSE, the edge attributes shouldn't be a 
problem, or is there something I'm missing?

thanks,
simone
