Yes, scrubber really does this. This dates back to Tokio and various
Japanese language emails which presumably weren't all ascii. Perhaps we
should revisit this, but you know much more about Japanese language
emails than I do.

Apparently, Tokio thought it was better to scrub such a part than to
treat it as ascii when it wasn't.

Perhaps a compromise is to give scrubbed text/plain attachments a .txt.
extension rather than taking the first item returned by
mime_types.guess_all_extensions.

Note that this is a Mailman 2.1 issue only. In MM 3 scrubber is only
invoked for plain text digests and just removes with notice all
non-text/plain elemental parts and for text/plain treats missing or
unknown charsets as ascii.
