[iconv] warning: invalid characters

Hi All,

While testing russian/mueller-dic at 11-CURRENT (as well as fresh
10.x) I get following lines (the port builds with base iconv):
-----
iconv -f koi8-r -t cp1251 -c
/wrkdirs/usr/ports/russian/mueller-dic/work/usr/local/share/dict/Mueller7accentGPL.ru_RU.KOI8-R
>
/wrkdirs/usr/ports/russian/mueller-dic/work/usr/local/share/dict/Mueller7accentGPL.ru_RU.CP1251
|| true
iconv: warning: invalid characters: 45385
-----

Full log is here:
http://gw.wart.ru/bulk/11-amd64-testing/2013-11-07_15h57m28s/logs/ru-mueller-dic-1.2_3.log

If built with libiconv from ports (i.e. for 9.x) the log does not
have a warning, full log:
