String values are returned as multibyte, e.g.:

(multibyte-string-p (cdr (assq 'severity (car (debbugs-get-status 22285)))))
=> t

because parsing happens in a temporary buffer where
enable-multibyte-characters is set, and the string value is returned
unchanged.

This is true for base64Binary values.

I'd like to change the base64Binary behavior back, but we can document
this nuance of the API.  Also, on the encoding side I think we should
force the caller to provide unibyte strings for base64Binary values.

Is the attached patch OK for master and emacs-25?
