That should be "jolly good", that is; what I was trying to say, was
that this works well, and therefore that I'm happy with it.

Even if there's nothing wrong? Anyway, here you go (it got quite lengthy):

There was nothing about Gcc there (see above).

Here I compose a followup to the message in mail.foo, but put in an
empty References header. This followup is split to mail.misc and not to
mail.foo:

This time I used "Ibsens ripsbusker" as subject:

ozelot:~$ grep -i "ibsens ripsbusker" .gnus.registry.eld
ozelot:~$

Nothing at all!
What if I restart Gnus? Ah, then there's something there:

ozelot:~$ grep -i "ibsens ripsbusker" .gnus.registry.eld
("<fqg8ye5zcbu.fsf@ozelot.stud.ntnu.no>" ((process (ham spam-use-stat 
"nnmaildir:mail.foo")) (mtime 16610 30770 60011) (subject . "Ibsens 
ripsbusker")) "nnmaildir:mail.foo" "nnmaildir:mail.misc")
ozelot:~$

OK, I went to the Article buffer of the message with an empty
References header and did that. Here's what the Messages buffer said:

--8<---------------cut here---------------start------------->8---
gnus-registry-split-fancy-with-parent (extra tracking) traced subject Ibsens 
ri\psbusker to group nnmaildir:mail.foo
gnus-registry-split-fancy-with-parent: too many extra matches for nil
nil
--8<---------------cut here---------------end--------------->8---

No, I agree with you. But in this case the Subject was unique. 

Another thing: Might it be an idea that the
gnus-registry-split-fancy-with-parent function consider the
In-Reply-To header if there is no References ?

Heres my nnmail-split-fancy in case it matters:
(setq nnmail-split-fancy
       '(|
         (: gnus-registry-split-fancy-with-parent)
; for the occasion        (: spam-split)
         "mail.misc"))
