ProtocolError: packet is not EOF

I am getting the following error when running in my local setup (mysql 5.5.40, ruby 2.1.5 on ubuntu 14.04):

$ mysql --version
mysql  Ver 14.14 Distrib 5.5.40, for debian-linux-gnu (x86_64) using readline 6.3

$ RAILS_ENV=production mysqltopostgres database.yml

MySQL config (nothing special):

[...]
mysql_data_source: &pii
  hostname: localhost
  port: 3306
  socket: /var/run/mysqld/mysqld.sock
  username: xx
  password: xx
  database: xx

mysql2psql:
  mysql:
    <<: *pii

[...]

Thanks! Thomas
