Why are Atom item titles not being returned using go-pkg-rss?

Question

Either I am losing my mind, I don't understand arrays of pointers, or the library is busted. Perhaps you can help. The following code seems to fetch Atom items just fine, but viewing their titles are coming back as empty strings.

(This happens to be implemented via http, I don't think that's the problem but of course anything's possible.)

package main

import (
    "fmt"
    rss "github.com/jteeuwen/go-pkg-rss"
    "net/http"
    "os"
)

var items []*rss.Item
var channels []*rss.Channel

func hello(w http.ResponseWriter, r *http.Request) {
    feed := rss.New(5, true, chanHandler, itemHandler)
    url := "http://stackoverflow.com/feeds"
    feed.Fetch(url, nil)
    fmt.Printf("Sent fetch for %s\n", url)
    fmt.Fprintf(w, "There are %d items in %s\n\n", len(items), url)
    for key, value := range items {
        fmt.Fprintf(w, "%d: %s\n\n", key, value.Title)
    }
}

func main() {
    http.HandleFunc("/", hello)
    http.ListenAndServe(":"+os.Getenv("PORT"), nil)
}

func chanHandler(feed *rss.Feed, newchannels []*rss.Channel) {
    channels = newchannels
}

func itemHandler(feed *rss.Feed, ch *rss.Channel, newitems []*rss.Item) {
    items = newitems
}

There is some bug with package "go-pkg-rss" about reading response.

There is a lot of similar packages, i tried to replicate your example with another one (it's simpler i think):

import (
    "fmt"
    "github.com/SlyMarbo/rss"
    "net/http"
    "os"
)

func hello(w http.ResponseWriter, r *http.Request) {
    url := "http://stackoverflow.com/feeds"
    feed, _ := rss.Fetch(url)
    fmt.Printf("Sent fetch for %s\n", url)
    fmt.Fprintf(w, "There are %d items in %s\n\n", len(feed.Items), url)
    for key, value := range feed.Items {
        fmt.Fprintln(w, key, value.Title)
    }
}

func main() {
    http.HandleFunc("/", hello)
    http.ListenAndServe(":"+os.Getenv("PORT"), nil)
}
