Okay, so `gnus-registry-clear' should probably also run
`gnus-registry-unload-hook'. You're not expecting the registry to be
doing it's thing when you've shut down Gnus, but are using debbugs,
right?

Would you try this definition:

(defun gnus-registry-clear ()
  "Clear the registry."
  (setq gnus-registry-db nil)
  (gnus-registry-unload-hook))

Huh, right after the definition of `gnus-registry-unload-hook' is this
line:

(add-hook 'gnus-registry-unload-hook 'gnus-registry-unload-hook)

I wonder what that's supposed to mean. Perhaps it should have been a
gnus shutdown hook, in which case you wouldn't have seen this error...

Anyway, I still think a gnus shutdown is a better place to have this.
