I can. It happens to any standard bounce message with this structure:

Content-type: multipart/report (whole message)
--
     Content-type: text/plain (human-readable text like "this is the 
mail system, I'm sorry...")
     --
     Content-type: message/delivery-status (About a dozen lines, all 
formatted like headers OR blank)
     --
     Content-type: message/rfc822 (wrapper object for an email message 
with all headers.)
     --
         Content-type: text/plain (the whole message as it was queued 
for transport. )

MM considers the two message/* parts to be "attachments" (i.e. if you 
QuickLook them you get an
unparsed "TextEdit" document and the original email message.) and they 
DO NOT get included as attachments in the forwarded message.

The obvious easy solution is to forward bounces as attachments rather 
than normally. That creates a multipart/mixed with a text part and a 
message/rfc822 part containing the whole  of the above structure, 
pristine.
