It might be because you were on Rails 2.2 or earlier and upgraded?

OldRails was for Rails <= 2.2, so you should probably try this instead:

  run ActionController::Dispatcher.new

This should use the pure Rack backend that avoids the old CGI
and CGIWrapper code which Rails <=2.2 relied on.

I haven't seen it before, but it looks to be on the right track.

OldRails uses the CGIWrapper code which is based on the original
code in Mongrel, too.

If you avoid CGIWrapper, you should be able to avoid the
workarounds/issues with it like the above gist.
