Rails - Mar 2010 - NoMethodError (undefined method `match' for nil:NilClass):

Hi,

I have a redmine server with Ruby 1.8 running along with Webrick. When I
try to access any docs on the server using web interface I get the
following message.

Internal error
An error occurred on the page you are trying to access.
If you continue to experience the problems please contact the
administrator.

I looked to production.log i found the following messages. I really need
your help. Thank you very much for your input.
