Subject: Possible bug: incorrect processing of multipart, base64-encoded subject lines.
Date: Wed, 21 Sep 2022 16:15:55 +0200	[thread overview]
Message-ID: <87wn9w4xus.fsf@thb.lt> (raw)

Hi all,

Notmuch doesn't parse correctly some Subject lines consisting of
multiple base64-encoded snippets.  As an example, this is the raw
subject line of an e-mail from Amazon:

Subject: =?UTF-8?B?TGl2cmFpc29uIHByw6l2dWUgcG91ciBhdWpvdXJk4oCZaHU=?=
 =?UTF-8?B?aTogUkVTVFJBUCBTYWRkbGUgQmFnIFNhY2NvY2hlLi4u?=

Notmuch displays the subject as only the decoded contents of the first
fragment (or first line), "Livraison prévue pour aujourd’hu", fully
ignoring the second base64 fragment, "i: RESTRAP Saddle Bag
Saccoche...".  The complete subject line should thus read:

> Livraison prévue pour aujourd’hui: RESTRAP Saddle Bag Saccoche...

Regards,
Thibault\r
