This bug was also reported in Ubuntu: https://bugs.launchpad.net/ubuntu/+source/php5/+bug/900620
The patch file attached is from Thomas Ward: https://launchpad.net/~trekcaptainusa-tw https://bugs.launchpad.net/ubuntu/+source/php5/+bug/900620/+attachment/2665282/+files/php-fpm-listen-on-unix-socket.patch This solves the issue, though it may require that apps that use php5-fpm change their connect arguments. Currently only phpmyadmin can be configured to use php5-fpm in the archive, though I'm sure there are many users who will have to change configurations on upgrade.
