Redmine

If I register a new user with very short password, I will get the error:

ActionView::TemplateError (Translation value "is too short (minimum is %d characters)" 
with arguments [] caused error 'too few arguments') on line #4 of account/register.rhtml:
1: <h2><%=l(:label_register)%></h2>
2: 
3: <% form_tag({:action => 'register'}, :class => "tabular") do %>
4: <%= error_messages_for 'user' %>
5: 
6: <div class="box">
7: <!--[form:user]-->
