Buggy boundary type in forwarded mail

Buggy boundary type in forwarded mail

Hi all,

a friend of mine and I semm to have discovered a bug in the gnus
boundary types when forwarding mails with attachment. 

I'll try to explain what happens.

The header of the mail defines <Boundary A> as boundary and the body
looks like:

[-- Attachment #1.2: Type: text/plain, Size: 401 bytes --]

--<Boundary A>
Content-Type definition; Boundary B definition

--<Boundary B>
Forwarding blabla... text... whatever

--<Boundary B>
forwarded mail; header defines <Boundary A2>

--<Boundary A2>
Text of forwarded mail

--<Boundary A2>
Attachment of forwarded mail

--<Boundary A2>--

<Boundary B>
End of my blabla

--<Boundary B>--
--<Boundary A>
GPG Signature
--<Boundary A>--

[-- Attachment #1.3: Type: text/plain, Size: 456 bytes --]


Unfortunately, A2 = A, although they *should* be different, I believe.

So this looks like the MIME signing part doesn't check properly
whether its boundary type is already used within the mail somewhere.

Regards,
Georg

There is code in there to check for this, but perhaps it's broken.
Could you post a message that will display this behavior when
forwarded by Gnus?
