This started happening a few days ago.  I would guess something has been
changed to not work in temporary buffers any more or something...

Ring any bells?  If not, I can try debugging further.

It's not just diff-mode.  It's any text attachments.  Here's an example:

Fixed the bug in files.el.  I think.  It assumes that file names are
absolute, and that's not the case when run from auto-mode etc.
