No, this is just the way IPCP works: you request to configure your
address to something, and if you have no clue that may be 0.0.0.0.

The peer then either ACKs this address or NAKs it with a better suggestion.

Here the peer didn't respond to the IPCP configure request at all, but instead
closes LCP (and thereby the whole session).

This is very, very strange.
