bug#34017: 26.1; emacs-w3m no longer works

[Art Werschulz]

When using vm to read mail in emacs, if the message has HTML mail, I get
the message
Inline text/html by emacs-w3m display failed: (wrong-type-argument stringp nil)
in the minibuffer.  Moreover, only the HTML source of the message
appears in the presentation buffer.

Note that this all worked up through last Friday.  I haven't changed my
emacs configuration since then, but we did upgrade from Fedora 28 to
Fedora 29.

bug#34017: 26.1; emacs-w3m no longer works

[Glenn Morris]

VM is not part of GNU Emacs or ELPA.
W3 is in GNU ELPA, but AFAICS is broken and unmaintained for years, ref

https://debbugs.gnu.org/25395#24

I would suggest you report this to the upstreams of these projects in
the first instance, and followup here if it turns out to be a core Emacs
issue.

Sorry, I mixed up w3 and w3m (not for the first time).
w3m is not in GNU ELPA.

So again, I suggest reporting this to whoever maintains those projects.

emacs-w3m and its Gnus integration (setq mm-text-html-renderer 'w3m)
works normally, so I'd guess this is VM problem, and should be reported
there.

Since this is not a problem in Emacs, I'm closing this as notabug.
