Yes.

But I didn't say that I would not expect the registry to work with
debbugs.  It would be good if it did - but I don't know if it's
technically possible.

Well, that fixes - only one error.  I still get an error from

  (defalias 'gnus-user-format-function-M
  'gnus-registry-article-marks-to-chars)

so I have to redefine that one, too.  And even after doing this I get an
error related to Gnorb:
