recvmsg bug: copied 0 seq XXXXX

I'm still getting this messages in kernel 2.2.13pre15.
The oldest message that appears in my logs is with a 2.2.12 kernel.
I don't know if they have appeared before.

This is a SMP box, ppp network (dialup connection). I have seen
the messages while using fetchmail and ftp.

The source says (net/ipv4/tcp.c):

/* Now that we have two receive queues this
* shouldn't happen.
*/
if (before(*seq, TCP_SKB_CB(skb)->seq)) {
printk(KERN_INFO "recvmsg bug: copied %X seq %X\n",
*seq, TCP_SKB_CB(skb)->seq);
break;
}

Should I be concerned?
