           Version: 1.13.5
          Platform: Ubuntu Packages
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: ralfjung-e at gmx.de

Recently, I am experiencing weird email display problems in KMail: The
displayed content starts with a part of the header, and the remaining text is
not properly decoded - in addition, the two parts of the email (text and HTML)
are both displayed on top of each other:

[quote begin]
Content-Type: text/plain; charset="iso-8859-1"

Content-Transfer-Encoding: quoted-printable

[...]

Mit freundlichen Gr=FC=DFen
[...]
--_000_917DECA9F3B4254BA11A0BE2BC4DE8E67782B33A98RLSGDC1rlsgff_

Content-Type: text/html; charset="iso-8859-1"

Content-Transfer-Encoding: quoted-printable

<html xmlns:o=3D"urn:schemas-microsoft-com:office:office" xmlns:w=3D"urn:sc=

hemas-microsoft-com:office:word" xmlns=3D"http://www.w3.org/TR/REC-html40" =

xmlns:ns0=3D"urn:schemas-microsoft-com:office:smarttags">

<head>
[quote end]

Due to a somewhat weird email forwarding setup ;-) I also have the same emails
available in GMX web interface, and they look all right there, and I can
properly switch between HTML and Text version.

The email source code at the end of the header looks like this:

[quote begin]
X-KMail-EncryptionState: N
X-KMail-SignatureState: N
X-KMail-MDN-Sent:  

--_000_917DECA9F3B4254BA11A0BE2BC4DE8E67782B33A98RLSGDC1rlsgff_

Content-Type: text/plain; charset="iso-8859-1"

Content-Transfer-Encoding: quoted-printable
[quote end]
Maybe KMail has an issue with that stale line in the header that has no content
after the colon? On the other hand, other emails from the same sender work
fine, and they use exactly the same encoding - there just is no 2nd newline
after that weird random series of characters (and between the two lines of the
header).

Reproducible: Sometimes

OS: Linux (x86_64) release 2.6.35-27-generic
Compiler: cc

I am using the bogofilter spam filter, set up with KMail's spam filter
assistant, maybe that is related?
I temporarily disabled the filter and am now waiting for emails fro those
problematic senders.
