twice chunked

[HajoLOcke]

Hello,

i use nginx 1.1.0 as balancer in front of some apache-server. In some
cases, where the apache is generating bigger pages it sends content as
chunked, nginx is adding a second "chunked" to http-response header.
This is confusing Browsers and looks like:

Transfer-Encoding: chunked, chunked

nginx is compiled with:
nginx: nginx version: nginx/1.1.0
nginx: TLS SNI support enabled
nginx: configure arguments: --conf-path=/etc/nginx/nginx.conf
--error-log-path=/var/log/nginx/error.log --pid-path=/var/run/nginx.pid
--lock-path=/var/lock/nginx.lock
--http-log-path=/var/log/nginx/access.log
--http-client-body-temp-path=/var/lib/nginx/body
--http-proxy-temp-path=/var/lib/nginx/proxy
--http-fastcgi-temp-path=/var/lib/nginx/fastcgi --with-debug
--with-http_stub_status_module --with-http_flv_module
--with-http_ssl_module --with-http_dav_module
--with-http_gzip_static_module --with-http_realip_module --with-mail
--with-mail_ssl_module --with-ipv6
--add-module=/usr/src/nginx-1.1.0-1/modules/nginx-upstream-fair


What can id do to avoid this double chunked in header? Parts of conf
needed? ( no special stuff in it)

Thanks,
Hajo
