This was reported on sage-support by Pedro Cruz:
{{{
sage: G = graphs.PetersenGraph()
sage: G.relabel( [ i+1 for i in range(G.order()) ], inplace=True )
sage: G.relabel( [ i+1 for i in range(G.order()) ], inplace=True )
}}}
This is because relabeling with a list as an argument only works when the
graph's vertices are {{{0,...,n-1}}}. With this branch this syntax always
works, by using for the graph's vertices the order given by
`G.vertices()`. Should not lead to any confusion I hope.
