Hi!

This message demonstrates a bug in gnus. It contains two text parts.
If you followup to this message, then gnus prepares a reply buffer
with correct To header:

To: Владимир Волович <vvv@vvv.vsu.ru>

But if you first press C-d, then followup to one of the parts, then
gnus prepares incorrect To header (already encoded!):

To: =?koi8-r?b?98zBxMnNydIg98/Mz9fJ?= =?koi8-r?b?3g==?= <vvv@vvv.vsu.ru>
