I traced a bit what could be wrong and found out that it's not in the
emacs part :

$ notmuch show --decrypt "subject:whatever"

[...]

header{
olivier.berger@it-sudparis.eu (20 mins. ago) (encrypted)
Subject: whatever
From: olivier.berger@it-sudparis.eu
To: whomever
Date: Wed, 11 Apr 2012 18:32:23 +0200

header}

body{
Failed to decrypt part: Canceled.

part{ ID: 1, Content-type: multipart/encrypted

part{ ID: 2, Filename: msg.asc, Content-type: application/pgp-encrypted
Non-text part: application/pgp-encrypted

part}

part{ ID: 3, Content-type: application/octet-stream
Non-text part: application/octet-stream

part}

part}

body}

message}


Dunno what happens. Anyone else ?

Thanks in advance.
