Looking at the kernel sources you will find : 
in : source/net/ipv6/icmp.c

345         /* 
346          *      Never answer to a ICMP packet.
347          */
348         if (is_ineligible(skb)) {
349                 LIMIT_NETDEBUG(KERN_DEBUG \"icmpv6_send: no reply to icmp error\\n\");
350                 return;
351         }

So this error tends to prove that the addressed ICMP packet was not correctly formed. The kernel says : \"this packet sux get off me ! ponk !\" and reject it.

Doesn\'t look like a serious error, it\'s much more like a debug message. 

This may occur a lot in spoofing attempts.

Hope this helps,
