           Summary: no longer possible to extract
                    SpamAssassin-encapsulated message
           Product: kmail2
           Version: Git (master)
          Platform: Compiled Sources
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: general
        AssignedTo: kdepim-bugs at kde.org

Test message

Version:           Git (master) (using Devel) 
OS:                Linux

SpamAssassin forwards suspected spam emails with a preview and description in
the message body, and the original message as an attachment of type
message/rfc822.  Using KMail from KDE3, if a message was wrongly detected as
spam by SA it was possible to view the original message attachment by clicking
on it, and then use the viewer's context menu "Copy Message To" to move it back
into the inbox so recovering the original message.

Now it appears that this is no longer possible.  Clicking on the attachment
prompts to either "Save as", "Open with KMail view" or "open with".  Clicking
"Open with Kmail view" does a bit of disc activity and then puts up the message
box "The file does not contain a message".

The attachment can be dragged to either the desktop or a Dolphin window, but
not to the inbox folder or anywhere else in Kmail (the "no entry" cursor is
shown).

RMB - View on the attachment opens it in a viewer window, but this has no
context menu so nothing can be done.

>From the message structure viewer, RMB - View over the attachment does exactly
the same as above.

In the viewer, the "Encapsulated message" header appears to be a link, but
clicking on it or using RMB - Open URL does nothing.


Reproducible: Always

Steps to Reproduce:
View a message with a message/rfc822 attachment.  Try to do something useful
with the attached message.


Actual Results:  
Impossible to extract the encapsulated message.


Expected Results:  
Should be possible to extract it, as in KDE3.


This is a local (not IMAP) maildir folder.

Attached is a test message that demonstrates this problem.  It has been
sanitised for personal information and is safe to open.  Your mission, should
you choose to accept it, is to get the original message into the inbox or any
other folder.
