           Summary: Crash while saving or opening an attachment of a mail
           Product: kmail2
           Version: unspecified
          Platform: Debian testing
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: crash
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org
        ReportedBy: dominic.schrader at gmx.net


Application: kmail (1.13.7)
KDE Platform Version: 4.6.2 (4.6.2)
Qt Version: 4.7.2
Operating System: Linux 2.6.38-2-amd64 x86_64
Distribution: Debian GNU/Linux testing (wheezy)

-- Information about the crash:
- What I was doing when the application crashed:

I got a mail with 3 attachments, but not all attachments are shown. The name of
the second attachment is displayed incomplete, at the bottom of the mail the
complete name of this attachment is shown, but it contains an quotation mark at
the end of the filename. If I try to open or save this attachment KMail crashes
immediately. When I press 'v' to show the code of the message the name of the
second attachment changes and contains several "%20" in the name, but the first
part of the filename is still missing. The third attachment is shown now with
%20 and a missing first part of the name, too. At the bottom of the page the
complete names of the attachments are shown without those %20 codes and it is
possible to open or save the attachment now. After opening another mail and
then opening this mail again, the mail is shown like before (without the third
attachment and the first version of the incomplete filename of the second
attachment) again.

This problem occurs on an IMAP-Acount on a Zarafa Server. When I use another
mail client the message is shown without any problems.

The headers of the second attachment:
--=_ZG_static
Content-Type: application/octet-stream; 

name="=?windows-1252?Q?Planned_Work_-_WF_2634447_-_2011-06-29_-_Dr._B=FClow_&_Masiak_GmbH.pdf?=";
 name*0*=windows-1252''Planned%20Work%20-%20WF%202634447%20-%202011-06-29%20;
 name*1*=-%20Dr.%20B%FClow%20&%20Masiak%20GmbH.pdf
Content-Transfer-Encoding: base64
Content-Disposition: attachment; 

filename="=?windows-1252?Q?Planned_Work_-_WF_2634447_-_2011-06-29_-_Dr._B=FClow_&_Masiak_GmbH.pdf?=";

 filename*1*=9%20-%20Dr.%20B%FClow%20&%20Masiak%20GmbH.pdf

And the third attachment:
--=_ZG_static
Content-Type: application/octet-stream; 

name="=?windows-1252?Q?Affected_lines_-_WF_2634447_-_2011-06-29_-_Dr._B=FClow_&_Masiak_GmbH.xls?=";
 name*0*=windows-1252''Affected%20lines%20-%20WF%202634447%20-%202011-06-29%20;
 name*1*=-%20Dr.%20B%FClow%20&%20Masiak%20GmbH.xls
Content-Transfer-Encoding: base64
Content-Disposition: attachment; 

filename="=?windows-1252?Q?Affected_lines_-_WF_2634447_-_2011-06-29_-_Dr._B=FClow_&_Masiak_GmbH.xls?=";
 filename*0*=windows-1252''Affected%20lines%20-%20WF%202634447%20-%202011-06;
 filename*1*=-29%20-%20Dr.%20B%FClow%20&%20Masiak%20GmbH.xls

The crash can be reproduced every time.
