My reply was:

   Hi

   I am "top-posting" as the content is not from Olivier's mail
   id:"87d31artti.fsf@inf-8657.int-evry.fr" but from my email
   id:"m2ipb2tjl8.fsf@guru.guru-group.fi"...

   For some reason notmuch emacs client references to my email instead
   of Olivier's when pressing 'V', any of the stash commands, reply or
   so on. Maybe that has something to do accessing the ical content
   (i.e. emacs client access the ical part from wrong message).

   Do others experience the same behaviour ?

When I hand-applied Aaron's patch and re-evaluated 
(defun notmuch-show-insert-part-text/calendar ...) and reopened
this thread those things I mentioned above started to work OK :)

Aaron: could you provide the patch in format suitable for git-am
so it could be easily applied (and hopefully quickly, provided
that we get reviewers to look at it immediately :)
