Software Deployment

Hi,

It seem that the preferences_master for Chrome 51 don't work.

When I install Chrome 51.0.2704.106 and I modify the master_preferences like this:

{
 "homepage" : "https://www.google.fr/",
 "homepage_is_newtabpage" : false,
 "browser" : {
 "show_home_button": true,
 "check_default_browser": false
 },
 "bookmark_bar" : {
   "show_on_all_tabs" : false
 },
 "distribution" : {
  "first_run_tabs" : [
    "https://www.google.fr/"
   ],
   "skip_first_run_ui" : true,
   "show_welcome_page" : false,
   "import_search_engine" : false,
   "import_history" : false,
   "create_all_shortcuts" : false,
   "do_not_launch_chrome" : true,
   "do_not_register_for_update_launch": true,
   "do_not_create_desktop_shortcut": true,
   "do_not_create_quick_launch_shortcut": true,
   "do_not_create_taskbar_shortcut": true,
   "make_chrome_default" : false,
   "suppress_first_run_default_browser_prompt": true,
    "msi": true,
    "multi_install": true,
    "system_level": true,
    "verbose_logging": true
 }
}

This master_préférences works very well with Chrome 45.

I expect at the 1st run, Chrome open 1 tab on https://www.google.fr/ . But with Chrome 51 at the first run , Chrome open 2 tabs (url chrome://chrome-signin/?access_point=0&reason=0 and  https://www.google.com/intl/fr/chrome/browser/welcome.html)
 and at the others run, chrome open chrome://chrome-signin/?access_point=0&reason=0 instead of  open https://www.google.fr/

Anybody use master_preferences with Chrome 51? am I alone to meet a problem with the configuration file for Chrome 51?

Thank you
