Sounds like a server bug. The body structure:

(
	("text" "html" ("charset" "UTF-8") NIL NIL "quoted-printable" 1224 16)
	("application" "octet-stream" ("name" "2154973550.pdf") NIL """" "base64" 65322)
	"MIXED"
)

The Content-Description is """" in the second part. Seems like the server doesn't escape quotes in the original header.

That'd be interesting to check what the Content-Disposition is set to there and confirm the above comment.
