I did the following:

1. Compose a new message
2. Sign and encrypt it
3. Try to send it

At that point, my SMTP server (Google) failed and the mail was stored to
the outgoing folder.

4. GO to the outgoing folder
5. Open the mail and send it again


Expected:

The mail is decrypted and then reencrypted on sending; or it is sent as
is.


Real result:

The mail is opened in its encrypted form, and on sending KMail tries to
encrypt it a second time.

Reproducible: Always
