Bug ID: 340602
Summary: KMail puts PGP/MIME signed attachments twice into the
same mail (doubling mailsize)
Product: kmail2
Version: 4.11.5
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: crypto
Assignee: kdepim-bugs@kde.org
Reporter: kolafl...@kolahilft.de
When sending an PGP/MIME signed (and optionally also encrypted) mail, including
signed attachments, KMail puts every attachment twice into the mail.
This double's the size of the mail!
Example mail body, created by KMail. You'll see, that the (very small) file
"blue-pixel.png" has become attached twice. But I attached it only once to the
mail.
