Probably you did something wrong, then. I have just tried it, it
properly keeps the vertex attributes:

library(igraph)
g <- erdos.renyi.game(20, p=1/40)
V(g)$name <- seq_len(vcount(g))
igraph.par("print.vertex.attributes", TRUE)
decompose.graph(g)[[4]]

This is R, but that should not matter. If you can send me some minimal
C code that reproduces your problem, then I can check it.
