Set the gnus-verbose to 10 and see what the Messages buffer says.

Depends.  I don't know if Gcc will write the article with the correct
message ID (but common sense says it should).  Again, see what the
Messages buffer says.  Maybe there's a place where I'm not calling
the right hook.

The registry keeps a lookup table of subjects related to message
IDs.  You need to check if that subject is in the registry at all
(grep your registry file, for instance) and then do 
t M-: (gnus-registry-split-fancy-with-parent) in the buffer of the
article (`t' will show the whole article).  With gnus-verbose set to
10, I need to know what the Messages buffer says.

There are some reasons why the subject lookup will fail, chiefly that
the same subject may be in various groups (but there are others, see
the function gnus-registry-split-fancy-with-parent).  If there's more
than one match for a subject, the lookup is considered a failure.  I
thought about this, and it seems to be the best way to handle multiple
groups.  I'm open to suggestions if you think otherwise.
