Make sure you have this post-0.5.1 patch by Paul Lieverse applied:

struct pbuf *
pbuf_dechain(struct pbuf *p)
{
  struct pbuf *q;

  q = p->next;
  if (q != NULL) { // LW: Fix by Paul Lieverse, 1-3-2002
    q->tot_len = p->tot_len - p->len;
  }
  p->tot_len = p->len;
  p->next = NULL;
  return q;
}
