This might be caused by evo-couchdb not being able to contact desktopcouch, which can be because of a few reasons. So to help us determine what's the problem, could you please quit thunderbird, and then, on a terminal, run the following:
$ killall -9 e-addressbook-factory $ export COUCHDB_DEBUG_MESSAGES=1 $ /usr/lib/evolution/e-addressbook-factory then run thunderbird again, and when you see those error messages again, please copy all the output in the terminal and paste it here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/841566 Title: Can not open Ubuntu One address book: "book backend is opening" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thunderbird/+bug/841566/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
