Looks like the main difference is this:

vs. this:

You see, there's several routes to deal with "multipart/signed" with a
"text/plain" part included.

1) (correct) check the signature and display the text/plain attachment.
2) (correct) see that it's multipart/* with a text/plain part and display
   the text/plain attachment inline
3) (correct but less friendly) see that it's multipart/* with a text/plain
   part and display each part as an attachment that can be saved. (better if
   the text/plain can be viewed)
4) (correct, but outdated) display everything inline because the MTA doesn't
   know MIME.
5) (wrong) see the multipart/*, but see that it's not multipart/mixed or
   multipart/alternative and pretend it's not there.

I guess MS Outlook Express opted for option #5 for some reason...

Guess this means I need to stop signing announcements with proper MIME
settings.  (because I'll bet that doing "Content-Type: application/pgp;
format=text; x-action=sign" gives Outlook Express coniption fits, too...)
