koute / cargo-web

If I have a crate (libp2p-core in my case) that depends on two different versions of the same crate (here rand), cargo-web panics. libp2p/rust-libp2p#1268 is an example.

I'm getting this same issue when using quicksilver, not sure which dependency is causing it.

I think the panic happens on this line

cargo-web/src/cargo_shim/mod.rs

Line 415 in 4dce450

assert!( dependency.resolved_to.is_none(), "duplicate dependency" );

Could we add to the panic messsage the dependency name?
