The mailing list for listmasters using Sympa

["Mail administrator, Otto J. Makela" <address@concealed>]

It seems that you can wedge a Sympa installation hard by trying to send
a message with UTF-16 encoded headers through it. We are running Sympa
6.1.4 but I don't think this has been fixed in the later releases, since
the problem stems from the perl cpan library Encode::MIME::Header which
still only supports UTF-8 in message headers.

http://search.cpan.org/~dankogai/Encode-2.49/lib/Encode/MIME/Header.pm

The symptom is that sympa.pl dies. Sympa will still accept messages,
but does not distribute them. Removing the wedged message helps and the
logjam gets cleared from the system.

At least, this is my initial analysis. Anyone else seen this happen?
