I have been able to import the email myself and reproduce the issue.

Looking at the source of the imported mail, it has the header:
> Content-Type: multipart/alternate; boundary="=-m7pctIXGHnNa8SIElS5Z"
which is wrong, it should be multipart/alternative, per rfc 1341 (and
later, up to rfc 2046)

It's true that it is used to specify alternate contents, but the right
name is multipart/alternative.

Reviewing the code, it is a bug of the pst importer, that sets the mime
to multipart/alternate rather than multipart/alternative.

I have opened bug 745 about this, along with the trivial fix as a merge
request:
https://gitlab.gnome.org/GNOME/evolution/issues/745
https://gitlab.gnome.org/GNOME/evolution/merge_requests/42

(hope it is right from a procedimental pov, though)


Joe, as you are using the evolution version packaged by Ubuntu 19.10 I
see a few options.
* You could switch to a newer version -with this bug fixed- based on
Flatpack.
* You could try to get Ubuntu maintainers to include this fix
* You could patch your own evolution version (this is a trivial fix, so
it'd be very simple)
* You could continue using the broken importer and deal with it fixing
the imported entries later. Just running the following sed command on
the folder containing the imported files would fix them:

sed -i  '0,/^$/ { s!^Content-Type: multipart/alternate!Content-Type:
multipart/alternative! }' *.evolution:*


Kind regards
