If you put (require 'gnus-art) into your .emacs and eval it, does the
problem go away?

I had a similar problem when running a newer emacs-snapshot with
notmuch. See this thread: id:"87d3aaqyur.fsf@eve.chaoflow.net"

I believe the actual bug is in gnus but I don't really like the loop on
error behaviour of notmuch. I would like to try and fix it but haven't
found the time.
