This is by design.  The attachment icon is meant to be displayed using  
as little system resources as possible.

It is a terrible idea to parse the contents of every message to  
determine whether it contains attachments.  In many cases, this can  
only be determined via a detailed analysis of the structure and/or  
downloading contents of a message part from the server.

The attachment icon is meant to be a compromise.  It is not meant to  
describe whether attachments, in the sense that a file can potentially  
be downloaded from the message, are present.  It instead describes  
whether attachments exist from a MIME point of view - namely, any  
message containing more than one part (i.e. a multipart message)  
contains attachments.

I have struggled off and on for awhile with myself whether to remove  
this flag entirely.  After thinking about it a bit more, I am  
seriously considering removing it.
