Thank you for your report.

This is not a bug, but a missing feature.  Rmail never supported
multipart email messages.  There's an effort to add this to Rmail in
the future, but for now, you will have to decode the base64-encoded
part manually, after typing `e' to make the message editable: mark the
encoded part, type "M-x base64-decode-region RET", then "C-c C-c", and
finally "M-x rmail-redecode-body RET utf-8 RET" to decode the text
into Emacs's internal character representation.
