Hello, 

I read bug report 48713 which seems to resemble 
my problem, but it is closed. 
My problem seems to be reproducible: 

It happens when I send a GPG signed message
with an attachment where the attachment is signed, too.  
No encryption is used.  

The encoding is nested in that case.
The version in my sentmail folder is ok, but the one 
that is received isn't.  I diffed the two versions 
and found out that there are *two* empty lines 
between the outer and the inner encoding headers 
that get compressed into *one* empty line, 
probably while in transit.  

I'm not sure what the RFCs say on this but 
I guess the problem will disappear if we have 
only one empty line to start with.  

Below is the relevant part of the original email:
