Description Friedrich W. H. Kossebau 2020-05-09 22:17:45 UTC

Some email just arrived on kde-i18n-doc-bounces@kde.org which is displayed to be from a user "<unknown>".

Seems the From: entry is not properly parsed, or needs help to handle some broken content?
---8<---
X-Mailer: Sun Java(tm) System Messenger Express 6.2-9.09 (built Jan  8 2008)
From: =?iso-8859-1?Q?=22I=F1igo_Salvador_Azurmendi=22?=
 <xalba@clientes.euskaltel.es>

Comment 3 Friedrich W. H. Kossebau 2020-05-10 13:46:34 UTC

Yes, the "dolphin incorrect string" mail.

Could my locale "de_DE.UTF-8" have any effect? Or the database used? Or the file being stored in mbox for me?

Looking at the test case you added, I see a string
--- 8< ---
QByteArray("=?ISO-8859-1?Q?I=F1igo?= Salvador Azurmendi <xalba@clientes.euskaltel.es>"
--- 8< ---
where the data I see in the raw file in my maildir (?) folder has this:
--- 8< ---
From: =?iso-8859-1?Q?=22I=F1igo_Salvador_Azurmendi=22?=
 <xalba@clientes.euskaltel.es>
--- 8< ---
with the second line starting with a space.

Forgot to mention other software versions:
Qt 5.14.1
KF 5.69
KDEPIM 20.04
(openSUSE TW)

Comment 4 Laurent Montel 2020-05-10 19:17:24 UTC

I fixed some bug in kmime last week.
Perhaps it's fixed now.
not sure.
Wait and see as 5.14.1 will be release in 4 days.

Comment 5 Friedrich W. H. Kossebau 2020-05-24 16:05:56 UTC

Today I upgraded to 5.14.1, and in the full email display in the From: line the name is now properly shown ("Iñigo ..."), so might be fixed with that version indeed.

Not yet in the folder listing though.

Possibly due to being data coming from Akonadi and being cached with the old broken string? "Update Foldeer (F5)" did not have any effect here, could that be related to the folder being a maildir(?) (local-mail) one? How could I trigger an update of the folder list?
