           Summary: KMail cannot correctly display subjects with UTF-8
                    characters encoded in quoted-printable fomat
           Product: kmail
           Version: unspecified
          Platform: Mandriva RPMs
        OS/Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: gambas at users.sourceforge.net


Version:            (using KDE 4.2.4)
Installed from:    Mandriva RPMs

The SMTP standard specified how to specify the charset and the encoding of the
"Subject:" header in a mail.

For example, here is a mail whose subject has UTF-8 characters encoded in
quoted-printable format:

Date: Sun, 19 Jul 2009 23:00:07 +0200
From: <gambas at users.sf.net>
Subject: =?utf-8?q?Test_du_composant_SMTP_de_Gambas_-_Des_caract=C3=A8r?=
 =?utf-8?q?es_bizarres_?_=E2=82=AC=C2=A4=C2=A7=C3=A6=C5=93=C3=9F=C3=B0?=
 =?utf-8?q?=C4=91=C2=BB=E2=80=9C=E2=80=9D=C2=AB_-_Test_d'un_sujet_en_ut?=

 =?utf-8?q?=C3=A8res_est_respect=C3=A9e_??=

KMail on KDE 3.5 and gmail.com perfectly displays that subject. But KMail on
KDE 4.2.4 displays that:
