The problem persits if Emacs is customized using mailcap-add Moreover, this deletion happens every time a mime part is decoded, because, as shown in this commit http://git.savannah.gnu.org/cgit/emacs.git/commit/lisp/net/mailcap.el?h=3De= macs-27&id=3Da5a967b43dd2810635d7a06ea70510c4a8e5c10f mailcap-mime-info involes mailcap-parse-mailcaps with "force" set to T every time Emacs tries to compute the list of viewers associated to a mime part -- does not matter whether the part is displayed inline or externally; the mere visualization of the email causes mailcap-mime-data to be erased. This bug breaks systems that do not rely on .mailcap for defining external viewers. In particular, it breaks systems that require pdf-tools or doc-view to view certain attachments. It also deletes Emacs' traditional association list betwee mime types and actions.
