FWIW, a " *temp*" buffer is only created in mm-util.el, in
`mm-find-buffer-file-coding-system'. My guess is that some mime handler
is calling an external process to do some sort of decoding of article
content or attachment, and that's somehow getting attached to the temp
buffer incorrectly.

Total guess!
