Hmm, I thought we had fixed that years ago.

This is a really ugly solution ... and I don't think it solves the
general problem anyway, since this isn't the only possible error message.

I don't seem to have gotten the original problem report, and the archive
page is pretty useless because all the non-ASCII characters have gotten
changed to "?".  Could you post a self-contained example case?  Might be
best to wrap it as a compressed attachment so it doesn't get munged in
transmission.
