A pdf file is attached to an e-mail message.
The message list says that the size of the message is 179 KB
But there is no little icon on the left of the pane indicating an attachment in the Subject column.
A header on the message says:
Content-Type: application/pdf;
  name="SysEng Technical Staff meeting - March 13, 2007.pdf"
The bottom attachment pane says that the file is 1012 B
The attachment cannot be saved or displayed.
This only happens if there is no other part of the message, for example, someone introduces the attachment. There is no "boundary" info in the message header.
