Sorry, my previous comment was wrong. This 'SimilarTypeTraits' should be
ParamTraits and we need to implement its methods as listed below. (I would
recommend them to add in 'webkit_param_traits.cc'.)

void ParamTraits<WebKit::WebString>::Write(Message* m,
                                           const param_type& p) {
  WriteParam(m, static_cast<string16>(p));
}

bool ParamTraits<WebKit::WebString>::Read(const Message* m,
                                          void** iter,
                                          param_type* p) {
  string16 string;
  if (!ReadParam(m, iter, &string))
    return false;
  p->assign(string);
  return true;
}

void ParamTraits<WebKit::WebString>::Log(const param_type& p,
                                         std::string* l) {
  LogParam(static_cast<string16>(p), l);
}
