Some such refactoring would be great.  It's a long-standing issue:

  http://bugs.squeak.org/view.php?id=6495

I haven't thought it through in a while, but my suggested refactoring
at the time was this:

    Errors should be reported better. One refactoring would be to make
    an "DownloadError" subclass of MIMEDocument. Then, we could
    robustly track which downloads are errors, without breaking
    compatibility with code that simply displays the result whether it
    was an error or not (e.g., Scamper).


Anyone interested in making a little ErroneousMIMEDocument class to
patch this up?
