How do applications in ubuntu pass the url to the browser?

I use Ubuntu 16.04 and Google Chrome. When some application requires opening a browser window, passing it a url, the browser opens a blank page. Other browsers are fine.

• check_common_commands http://ya.ru
• '[' 1 -gt 0 ']'
• parm = http://ya.ru
• shift
• case "$ parm" in
• '[' 0 -gt 0 ']'
• '[' -z '' ']'
• unset XDG_UTILS_DEBUG_LEVEL
• '[' 0 -lt 1 ']'
• xdg_redirect_output = '> / dev / null 2> / dev / null'
• '[' xhttp: //ya.ru '! =' x ']'
• url =
• '[' 1 -gt 0 ']'
• parm = http://ya.ru
• shift
• case "$ parm" in
• '[' -n '' ']'
• url = http://ya.ru
• '[' 0 -gt 0 ']'
• '[' -z http://ya.ru ']'
• detectDE
• unset GREP_OPTIONS
• '[' -n Unity ']'
• case "$ {XDG_CURRENT_DESKTOP}" in
• '[' x = x ']'
• '[' x '! =' x ']'
• '[' xthis-is-deprecated '! =' x ']'
• DE = gnome
• '[' xgnome = x ']'
• '[' xgnome = x ']'
• '[' xgnome = xgnome ']'
• which gnome-default-applications-properties
• DE = gnome3
• '[' xgnome3 = x ']'
• DEBUG 2 'Selected DE gnome3'
• '[' -z '' ']'
• return 0
• case "$ {BROWSER}" in
• case "$ DE" in
• open_gnome3 http://ya.ru
• gvfs-open - help
• gvfs-open http://ya.ru
• '[' 0 -eq 0 ']'
• exit_success
• '[' 0 -gt 0 ']'
• exit 0

In other browsers, everything works fine. In addition, in the parameters of the google chrome system, the browser can not be selected by default, perhaps ubuntu does not see it or sees it incorrectly.
