problems with multipart/mixed

[Matthias Guedemann <matthias.guedemann@ovgu.de>]

Hi all,

I am using notmuch / emacs as my main mail client now for several months
and loosely follow master.

After an update yesterday I now have problems with some multipart/mixed
mails from mailing lists which are displayed for example as follows (I
could also provide the raw mail if needed):

i.e. the html part is not displayed. I'd like to have it displayed
inline (using w3m), just as other html mails and just like it worked
before (at least I think it worked). I probably just missed a simple
configuration option.

My notmuch config in .emacs (and my message mode config) is at the end
of this mail. From the git logs I saw that there have been some changes
to multipart handling and new variables, but I could not really find a
solution.

Perhaps someone can point out where my current config is broken.

best regards
Matthias
