Is that with NM git master, and if so, what date? The reason I ask is because we broke PtP addresses until 2013-12-02, fixed in commit f099a04132241790c8f88a651ece49f5c2783d12. The error you're getting may well be the kernel complaining that it cannot reach the static route, because it knows nothing about the next hop, because the PtP address wasn't assigned correctly.
