No TV artwork in Krypton

I made a new installation of Krypton from scratch on Raspberry Pi 2. Everything works great, except the TV artwork.

I’ve added both TV shows and movies through NFS, and I’ve set the content accordingly. I get the artwork for the movies. For the TV shows I get the information but no artwork. Instead I get a placeholder picture. When I try to choose artwork myself through the context menu and Information, I only see placeholder pictures.

I’ve tried deleting the source and adding again with the same result.

Any idea what to do?

Looks like I’ve found the problem. After changing the scraper from The TVDB to TMDB I get all the artwork. I guess something is wrong with The TVDB.
