Gconf proxy setting issue
Gconf proxy setting issue

In case of /system/proxy and /system/http_proxy don't exist
in gconf directory, use gconf_client_set_* to set the inital
value for proxy settings. If proxy is configured by external
application, such as browser standalone setting, it will
receive value changed signal and change internal proxy setting
event for the first time.
