****************************************************************

After decryption, the ciphertext results in an embedded MIME message, which in turn contains an attachment.

The embedded message is displayed after decryption, including the attachment which is shown as a link the message window, but the message structure view displayed by kMail does not change and the attachment link is not effective, clicking it is a no-op.

Actually there seems to be no way to save the deencrypted attachment using kmail2. This worked file with kmail 1.

Reproducible: Always

Steps to Reproduce:
Receive an exncrypted message structures as described above.

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.
