Comment 8 for bug 872639

This message means couchdb-glib couldn't find the token for Desktopcouch in the keyring. So I guess this is a desktopcouch problem we've seen a few times, that either it doesn't start (could you test this by trying to run /usr/lib/desktopcouch/desktopcouch-service on a terminal and see if it shows up any error?) or even though it does start, it doesn't sync the tokens in the keyring, so couchdb-glib doesn't know how to authenticate at all.

So, follow the instructions at the 'killing and restarting dc' section at http://www.freedesktop.org/wiki/Specifications/desktopcouch/Documentation/Troubleshooting and let's see if it's that, but it really looks like it indeed is, since that message comes from here:

http://git.gnome.org/browse/evolution-couchdb/tree/addressbook/e-book-backend-couchdb.c#n1099

and the only way desktopcouch_session_new can fail is because of it not being able to contact desktopcouch or finding the tokens in the keyring:

http://git.gnome.org/browse/couchdb-glib/tree/desktopcouch-glib/desktopcouch-session.c#n57

So either desktopcouch is not installed or not being started correctly, or it's not writing the tokens to the keyring.
