  And what if the pointer contained in tag isn't the same as the local
pointer for (gchar*) "artist" ? This is basic pointer 

  And that check is useless anyway, you can directly do ...

    if (gst_tag_list_get_string_index(list, GST_TAG_ARTIST, 0, &str)) {
      g_print("%s : %20s\n", GST_TAG_ARTIST, str);
      /* Do something with str */
      g_free (str);
    }

    ... without the need to call gst_tag_list_foreach(). If there's no
GST_TAG_ARTIST in that list it will return FALSE, and if there's one it
will return the first occurence.
