You can get a better handle on this by splitting the above lines into
multiple lines, so something like
<% all_privileges
=privilege_tag.privileges.all(:conditions=>"name<>'FinanceControl'",:order=>"priority
ASC") %>
<% all_privileges = all_privileges.select{|p| p.applicable?} %>
Then you can find which bit is causing the error.
What is p.applicable?
