Bug under 2.3.1 Custom field tracker configuration does not work

[1SuperGrobi]

If you have an custom field that belongs only to one tracker,
than it is shown (creating a new ticket) at every tracker when it belongs to the first (default) tracker.
Otherwise it is shown never.

I changed the file "app\views\issues\update_form.js.erb" the following way and know it seems to work.

$('#all_attributes').html('<%= escape_javascript(render :partial => 'form') %>');

<% if User.current.allowed_to?(:log_time, @issue.project) %>
$('#log_time').show();
<% else %>
$('#log_time').hide();
<% end %>

preparePasteEvents();
