"Add to contacts" doesn't work

After receiving an SMS from someone that was not in my contacts, I decided to add him to my contacts.

In the conversation's menu, I selected "Add to contacts" but nothing happened.

In the logs there was the following error :

pureos gnome-contacts[15955]: Error retrieving accessibility bus address: org.freedesktop.DBus.Error.ServiceUnknown: The name org.a11y.Bus was not provided by any .service files
