What is it about the PGP/MIME spec that makes it not
play nicely with HTML email?  Or vice versa?

I'm not sure, but it seems no MUA or plug-in I have tried handles it correctly.

I've always assumed that lack of HTML support said
more about the crypto crowd's preference for text
email than some technical problem, but perhaps I was
wrong...

This very well may be the case; it could just be an implementation
issue. PGP/MIME seems to be based on RFC1847, which states:

  ...The first body part may contain any valid MIME content
  type, labeled accordingly...

So, it would seem the "first body part" could be of type
multipart/alternative (HTML). But I am unsure; as
multipart/alternative is needed in the message header of an HTML
email. RFC 1847 requires "multipart/signed" or "multipart/encrytped"
in the message header. I think that may be what causes the troubles.

Whatever the case, I always seem to have issues with attachments and
HTML messages using PGP, but not with S/MIME. Although that may be a
result of the limited selection of MUAs and software I use at my
company. (Thuderbird, Outlook+GPGOL and Outlook plus the commercial
PGP Desktop v9).
