            Bug ID: 485279
           Summary: Drag-and-drop from the mail reader doesn't work for
                    mails that consist of only the attachment
    Classification: Applications
           Product: kmail2
           Version: 5.24.5
          Platform: NixOS
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR

SUMMARY
Dragging a file out of the mail reader only creates a broken desktop entry for
mails that have headers Content-Disposition: attachment. Mails containing DMARC
reports from Google are formatted this way, for example.

STEPS TO REPRODUCE
1. Open mail which consists only of the attachment
2. Drag attachment onto desktop

OBSERVED RESULT
It creates a file named "attachment:?place=body". When you try to open it, an
error dialog saying "Could not read file attachment:?place=body." pops up.

EXPECTED RESULT
Drag-and-drop works like for attachments in a multipart email.
