That's a perfectly legitimate Subject: line...  RFC822 lists the Subject:
header as *text, where text is

   text        =  any CHAR, including bare    ; => atoms, specials,
                  CR & bare LF, but NOT       ;  comments and
                  including CRLF>             ;  quoted-strings are
                                              ;  NOT recognized.

a CHAR type is any ASCII character in the numeric decimal range of 0-127.

So, to reiterate, folding Subject: headers are valid...
