Aah, I see that it's not malformed; the relevant code in 
netinet/if_ether.c says

         if (la == 0 || rt == 0) {
                 log(LOG_DEBUG, "arpresolve: can't allocate llinfo for 
%s%s%s\n",
                         inet_ntoa(SIN(dst)->sin_addr), la ? "la" : "",
                                 rt ? "rt" : "");
                 m_freem(m);
                 return (0);
         }

I still don't understand why this is happening, though, so clues would 
still be welcome.
