I.m using version 1.9.3 final.
It's a problem because 1.9.4 RC2 is a priority now.
By the way I got 3 e-mails on your post. It appears that the language being use is Russan. Some english is in the body of the e-mail.
This is a problem, because you are getting notifications in a post author culture and 3 times somehow.
P.S. Your site looks quite fine.
