Form_tag cause error on production

dear, I just deployed my first rails application and it failed

when I checked the log file on the server, i got the following

ActionView::TemplateError (wrong argument type FalseClass (expected
Proc)) on line #13 of daleel/_top.html.erb:
10:
11:
12:


13: <% form_tag :action => :navigate do %>
14:
15:

any idea why is it behaving like that
on my localhost
there is no error in development and production env

thanks

Have a look through the group archives, but I have a vague
recollection that ruby 1.8.6 p230 does that.

Well
I do not find any useful info on google search
I am just wondering why the server fails on this part of the code.
However, sometimes it works.

Strange???
