gunicorn 19.0 broke the tornado worker

[g-p-g]

After upgrading to gunicorn 19.0 the tornado worker which used to work with gunicorn 18.0 no longer does. It looks like the x_forwarded_for_header setting is no longer present in cfg (gunicorn.workers.gtornado.TornadoWorker @ run ~ line 95 or so), what's the expected way to use the new version?

[ERROR] Exception in worker process:

@benoitc looks like we broke tornado for real. We should do a quick fix release.

@tilgovi fixed. I will make a release today .

@g-p-g thanks for the report

@benoitc that fix looks strange for an outsider as the removed line used to work before. Could you possibly point to some commit(s) that modified that behavior so it's no longer necessary to deal with X-FORWARDED-FOR in the tornado worker? Thanks.
