How get more debug info for “No information found for item…”

I have a problem where a show I have episodes for is getting:

Code:
07:59:23 T:140633813518080 WARNING: No information found for item '/video/mythvideo/Television/The National/', it won't be added to the library.

But even in debug mode I can’t seem to get more information about *why* it’s happening. The TVDB entry for the show is:

http://thetvdb.com/?tab=series&id=284879&lid=7

and as you can see, it has no episodes. That’s probably because it’s a daily news show. But my scraper for those episodes creates their own .nfo files such as:

Code:
<?xml version='1.0' encoding='UTF-8'?>
<episodedetails>
  <title>22:26:13-2016-10-02 The National - Full Show - The National for October 02, 2016</title>
  <showtitle>The National</showtitle>
  <season>2016</season>
  <episode>276</episode>
  <uniqueid>2016276</uniqueid>
  <aired>2016-10-02</aired>
  <runtime>50</runtime>
</episodedetails>

And I have created a tvshow.nfo file for the show:

Code:
<?xml version='1.0' encoding='UTF-8'?>
<tvshow>
  <title>The National</title>
  <rating>8.8</rating>
  <year>2014</year>
  <plot>The news!</plot>
  <episodeguide>
    <url>http://thetvdb.com/api/9DAF49C96CBF8DAC/series/284879/all/en.zip</url>
  </episodeguide>
  <episodeguideurl>http://thetvdb.com/api/9DAF49C96CBF8DAC/series/284879/all/en.zip</episodeguideurl>
  <mpaa />
  <id>284879</id>
  <genre>News</genre>
  <premiered>2002-10-01</premiered>
  <studio>CBC</studio>
</tvshow>

But clearly there is something that the metadata scraper doesn’t like. So how do I get more detailed debug about what exactly it doesn’t like?

What makes all of this very odd is that these .nfo files have worked for many months until now.
