You have to save the registry file ('s' in the group buffer will do
it, if your newsrc.eld needs to be saved - the registry is saved
whenever the newsrc.eld is saved).

Excellent.

In gnus-registry.el, change line 420-423 to look like this (line to be
added marked with +):

(unless (equal res (gnus-registry-fetch-group key))
  (setq single-match nil))
+(debug single-match subject this-subject res (gnus-registry-fetch-group key))
(setq res (gnus-registry-fetch-group key))

Then re-evaluate the gnus-registry-split-fancy-with-parent function,
and re-run it for the article in question.  If you get more than one
debug call, the article subject is in multiple groups somehow.  If
you get just one, there's a bug.

If you send me your registry file, I may be able to do more debugging
too.

We already do that in gnus-registry-split-fancy-with-parent:

(message-fetch-field "in-reply-to")

is it not working correctly?
