Redmine

The following Problem arises when klicking on administration/users:

ActionView::TemplateError (undefined method `anonymous_user_path' for #<ActionView::Base:0x424b3ee8>) on line #42 of app
/views/users/index.rhtml:
39:     <td class="last_login_on" align="center"><%= format_time(user.last_login_on) unless user.last_login_on.nil? %></
td>
40:     <td class="buttons">
41:             <%= change_status_link(user) %>
42:             <%= link_to(l(:button_delete), user, :confirm => l(:text_are_you_sure), :method => :delete, :class => 'i
con icon-del') unless User.current == user %>
43:     </td>
44:   </tr>
45: <% end -%>

Rendering /var/www/redmine-svn/redmine/public/500.html (500 Internal Server Error)

But im able to mchange the url to http://.../users/x and see the user details and can change settings whithout problems for all ids >=6

Im Using apache/fcgid/mysql on version Redmine 1.1.1.devel.4798 (MySQL).

svn status shows only minimal changes, where 'update_redmine' is a script to backup und 'svn up' to the latest version.

root@home:/var/www/redmine# svn status
?       update_redmine
M       config/environment.rb
!       public/dispatch.fcgi.example
?       public/themes/holo

I Think it is a problem with the database and migration. Im using the devel version without problems since 2006.

Everything else is fine... where is the problem???
