            Bug ID: 300937
          Severity: normal
           Version: unspecified
          Priority: NOR
          Assignee: kdepim-bugs at kde.org
           Summary: Attachments within S/MIME mails which are "both"
                    encrypted and signed cannot be saved
    Classification: Unclassified
                OS: Linux
          Reporter: yuricbs at gmail.com
          Hardware: Ubuntu Packages
            Status: UNCONFIRMED
         Component: crypto
           Product: kmail2

Attachments within S/MIME mails which are "both" encrypted and signed cannot be
saved. Below follows an example of some fields of the e-mail header:

Content-Type: application/pkcs7-mime; name="smime.p7m";
smime-type="enveloped-data"
Content-Disposition: attachment; filename="smime.p7m"
Content-Transfer-Encoding: base64
MIME-Version: 1.0

I have verified the same problem even when the mail is sent from different
clients (Outlook or KMail itself).

This is similar to Bug 294272, but in this case it is related to S/MIME
messages which are "both" signed and encrypted. If the message is only signed,
or only encrypted, the problem does not occur.


Reproducible: Always

Steps to Reproduce:
Receive an S/MIME message, which is both signed and encrypted, containing an
attachment.
Actual Results:  
An attachment is displayed as a link inside the message window, but the link
cannot be opened / downloaded. There does not seem to be any way to view or
save the attachment.

Expected Results:  
The link / attachment should be downloadable / saveable.

Similar to Bug 294272, but in this case it is related to S/MIME messages which
are both signed and encrypted. If the message is only signed, or only
encrypted, the problem does not occur.
