EDIT: Anybody else has any suggestions? I'm totally stumped!!!

I have an app in which all the assets compile just fine but in this second app, when I run:

RAILS_ENV=production rake assets:precompile --trace

I get the following message: undefined method `directory?' for nil:NilClass

Please help. When I look under the public/assets directory I see that the image files have been precompiled but none of the js or css files.

Below is the full terminal output:

Thanks to phoet: I just surrounded those lines with an begin..rescue block at .bundle/ruby/1.9.1/gems/sprockets-2.0.2/lib/sprockets/base.rb. The error was caused by an invalid symlink (only in production env with rails 3.1.1 sprockets 2.0.2, additionally rack 1.3.4 caused an constant WFKV_ warning but rack 1.3.3 doesn't)

120  paths << path
121  begin
122    if stat(path).directory?
123      each_entry(path) do |subpath|
124        paths << subpath
125      end
126    end
127  rescue
128    puts "error with directory #{path}"
129  end

Now the error is gone and bundle exec rake assets:precompile --trace comes to an end, but needs an eternity at the last two steps ** Execute assets:precompile:primary right after tmp:cache:clear ... we will see ;)
