I found it.

The subjects were slightly differents, with a single trailing
whitespace at the end. I now use the gnus-simplify-whitespace function
to get rid of it, with the following in my ~/.gnus:

(setq gnus-simplify-subject-functions '(gnus-simplify-subject-re 
                                        gnus-simplify-whitespace))

It works well. :-)
