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.
