Did you know where does this version comes from?  Is there a packet's version, or whatever?

It's really strange that an "Update" message could fail.  After a quick look at the code, I think it should fail at line 513.  Could you see if changing

                if(!have_v4_nh)
                    goto fail;

to something like

                if(!have_v4_nh) {
                    fprintf("Don't have v4 nexthop.");
                    goto fail;
                }

confirm this hypothesis?
