Comment 2 for bug 666404

I'm not as skilled as Peter, but looks like this bug or something similar affects me (on more than one pc).
As a first configuration of evolution contacts, I imported a csv address book (about 200 entries). After trying (import/delete) some input formats, all contact details look fine. After some time I cannot delete any contact from evolution, always getting "Other error" (in Italian as expected). There are also a couple of empty contacts.

I tried to fix the issue following some indications on ubuntu forums (deleting couchdb entries from gnome-keyring, uninstalling evolution-couchdb, deleting config file and local address book from my home directory, installing evolution-couchdb again).

Now remote Ubuntu One contacts are no more downloaded. Creating two new contacts results in new undeletable entries.
