Comment 4 for bug 301013

http://emesene.org/trac/ticket/1449
I confirmed one error in translation file.

The error is in these lines,
 line1570 : msgid "You have %(num)i unread message%(s)s"
 line1571 : msgstr "%(num)i 件の未読メッセージがあります"
Second argument 's' does not exist in msgstr.
But Japanese language does not need the nominal plural form.
I think that there is no other way.
