The problem is the code after the comment "Remove empty parts" in
`mm-preferred-alternative-precedence'.  If I remove this code, it works
as before.

The messages I'm referring to in my original post are of type
"multipart/alternative", containing a "text/plain" and a
"multipart/mixed" part.  The latter part typicalle consists of a
"text/html" part and one or more attachments, e.g., "application/pdf".
When displaying such a message,

  (mm-handle-buffer handle)

returns the string "multipart/mixed" instead of a buffer, and
`with-current-buffer' then raises the error above.

Does really nobody else encounter this problem?

Best regards
