Base DAO exception (concatenate field)

I'm receiving the following exception when creating a plugin:

curl -d "name=authentication&api_id=ID&value={\"authentication_type\":\"query\"}" 127.0.0.1:8001/plugins/

Apparently the problem has been fixed with #37 and cannot be reproduced anymore. Closing now, it can be re-opened if it happens again.
