The message is broken. If you look at RFC 2045, what it comes down to is that '/' character cannot be in the value unless the whole value is "quoted". So this isn't a Dovecot bug, but anyway Dovecot v1.2+ happens to parse this in the way you want because it uses a different RFC 2231 parser, which just happens to parse this in a more forgiving way.
