The bug is about the fact that it doesn't work when gnome-control-center-signon is not installed. I don't use stock Ubuntu, I use ubuntu gnome so I don't want gnome-control-center-signon. gnome-control-center-signon is the configuration tool for Ubuntu-Online-Accounts not for Gnome-Online-Accounts (as you know those are 2 different things).
So, there is a way to configure Empathy accounts through Ubuntu-Online-Accounts, but there is no way to confirgure them when using Gnome-Online-Accounts.
As I said in https:/ /bugs.launchpad .net/ubuntu/ +source/ empathy/ +bug/1060060 (now marked as a duplicate of this one):
