Bug ID: 501794
Summary: application/pkcs7-mime attachments are not detected
Classification: Applications
Product: kmail2
Version: 6.3.2
Platform: Debian unstable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: UI
Assignee: kdepim-b...@kde.org
Reporter: daniele-...@gobbetti.name
Target Milestone: ---
SUMMARY
I'm experiencing an issue with an email with an attachment with Content-Type:
application/pkcs7-mime;. Kmail is NOT showing any attachment to this message,
but is showing the textual content followed by "this message is encoded.
("Questo messaggio è cifrato." in my localization) and a link to decode it.
This is the link as it appears in message view -> view source -> HTML source:
```
<a href="kmail:decryptMessage" style="display: inline-flex; align-items:
center;"> <img src="file:qrc:/icons/breeze/actions/16/document-decrypt.svg"
height="48" width="48"> Decifra il messaggio </a>
```
Once I click the link the signature is checked and its status is shown, but the
underlying file is not shown and even right-clicking in the message window and
choosing to save attachments does not work (popup is shown that there is no
attachment)
The full headers of the part are:
```
Content-Type: application/pkcs7-mime;
name="somedocument.docx.p7m"
Content-Transfer-Encoding: base64
Content-Disposition: attachment;
filename="somedocument.docx.p7m"
```
I saved the message to disk and extracted the attachment with munpack without
issues.
STEPS TO REPRODUCE
1. Open an email with an attachment with mime type "application/pkcs7-mime"
2. Click the link "kmail:decryptMessage"
OBSERVED RESULT
The signature of the attachment is checked. No attachment is shown or detected.
EXPECTED RESULT
The attachment can be opened / exported / saved to disk.
