GPGMail: Message with multipart/mixed encrypted attachment appears blank

I received a multipart/mixed message with unencrypted text and an encrypted attachment.
The message appears as signed and encrypted, but neither the text nor the attachment shows up in the message.

A workaround is to "View Raw Source" and then use GPG to decrypt the attachment.

The raw source looks like:

HEADERS
Content-Type: multipart/mixed; boundary=NONCE1

--NONCE1 Content-Type: text/plain; charset=UTF-8

PLAIN TEXT MESSAGE

--NONCE1 Content-Type: application/pgp-encrypted; name="FILENAME.gpg"
Content-Disposition: attachment; filename="FILENAME.gpg"
Content-Transfer-Encoding: base64
X-Attachment-Id: NONCE2

BASE64 GPG CONTENT
--NONCE1--

Expected
The text part appears, whether signed or encrypted or plain text.
The attachment appears, whether signed or encrypted or plain text.

For bonus points: The signed and encrypted part should be visually distinguished from the unsigned plaintext part, and the message itself is identified as mixed content.

   I can't send you the message I received, and I can't reproduce this issue using Mac Mail. Perhaps it's something that mutt does?

   Could you ask your contact using Mutt for additional test messages which you could then share?
