I was sort of wondering how I could proceed in debugging it myself but
of course I am happy to have others look at it too.

You'll find it attached.  I've also added in comment that is an example
of a subject that was not threaded.

multipart.sl (text/plain, 2.4 KB)

% This macro makes use of subject_compare_hook to put multipart binary
% postings into the same thread.
% Based on a script by Jurriaan Kalkman <[email protected]>

% try to determine if two headers belong to the same multipart
% posting. Return 0 if they do, 1 if they don't
%
% we assume headers use a number in [] or in () to tell us what
% part of a multipart-posting this is.
%
% This is an example of what is not being threaded:
