[VM] VM not handling inline HTML mail

[Patrick Healy]

I upgraded my Debian distro yesterday and I am now getting the following
message:
"Inline text/html by emacs-w3m display failed: (wrong-type-argument stringp nil)"

I note that this was reported as an issue by agw in January of this
year. I wonder if anybody has a fix for it?

Many thanks, though apologies for abusing an 'info' channel.

Which emacs version are you using and which verision of viewmail? And
what are your settings for the various vm-mime-* vars?

No apologies needed!

Happy to try and help you.

Thanks for you offer of help, John.

Here are the versions I'm using
emacs-version: 26.1
vm-version: 8.1.2

and on searching my .vm.el setup I find the s-expressions below.

Many thanks.

Hi Patrick,
Work has sucked all my free time lately, so I haven't had a chance to
try to look at this in more detail to help you.

The best thing would be to reset your environment down to the basics
and then try to add back in parts as needed.

I'm going to do this too, since I can't get the shr mode HTML decoding
to work in my patched 8.2.0b that I've been playing with.

If someone could provide a working patch... maybe we could get 8.2.0c
released?

John
