gnome-terminal ignores /system/http_proxy/host gsetings key

[Michal]

When I set manual proxy configuration, and run gnome-terminal, after running "env | grep proxy" i get no "http_proxy" environment variable set:
----8<----

michal@michal-c1:~$ env | grep proxy
ftp_proxy=http://myproxyhost.com:8000/
FTP_PROXY=http://myproxyhost.com:8000/
ALL_PROXY=socks://myproxyhost.com:8000/
all_proxy=socks://myproxyhost.com:8000/
https_proxy=http://pl.proxy.lucent.com:8000/
HTTPS_PROXY=http://myproxyhost.com:8000/
no_proxy=localhost,127.0.0.0/8
----8<----

After some investigation, I found, that when setting proxy in manual mode, the host and port configuration for protocols https, ftp and socks is stored in the "/system/proxy/" gsettings path, while http protocol, the host and port is stored in the "/system/http_proxy/".
Looking at the gnome-terminal code, the CONF_HTTP_PROXY_PREFIX is not used in the code at all, only declared in:
src/terminal-util.h:#define CONF_HTTP_PROXY_PREFIX "/system/http_proxy"
