Comment 3 for bug 727370

Nearly the same here:

Evolution isn't showing my ubuntuone contacts even if they clearly are synced - and if I go to the addressbook view I get an error message:

Address book could not be opened.
Detailed error message: GDBus.Error:org.gtk.GDBus.UnmappedGError.Quark._e_2ddata_2dbook_2derror.Code100: Cannot open book: Could not create DesktopcouchSession object

Normally the messages end here and I don't get informed about why the addressbook from couchdb cannot be read. Today I got the following error message instead:
** (e-addressbook-factory:14223): WARNING **: Could not get OAuth tokens from keyring: No matching results
Bye.

That couchdb worked until this evening is shown by the next command:
gunter@book:~/Desktop$ python ubuntuone-desktopcouch-admin.py -l
