Thunderbird is buggy then.  There is no attachment in either message.

This is what the MIME structure looks like for the BMP message:

multipart/related
   multipart/alternative
     text/plain
     text/html
   image/bmp

The image/bmp MUST somehow be referred to in either text/plain or  
text/html (the "root" part of the multipart/alternative).  The whole  
point of multipart/related is that the ENTIRE part can be represented  
in a single data object.  multipart/related does not allow attachments  
inside of it - that simply doesn't make any sense.

If Thunderbird is showing this part, its attachment recognition  
algorithm is badly broken (which is true, as previously mentioned when  
discussing forwarding).
