Hi Stephan,

I've heard (but not confirmed myself) Rails 3 doesn't work well with
Ruby 1.9.1, but does with 1.9.2dev (trunk), and 1.8.7.  Can you give
either of those versions of Ruby a try?

Another thing that's probably not the issue here, but since config.ru is
present, give "unicorn" a shot instead of "unicorn_rails" as the latter
hasn't been tested heavily with Rails 3.  "unicorn_rails" was designed
with older Rails in mind.

Let us know what you find, thanks!
