JSON REST APIs return LCB_SUCCESS with corrupt data

When performing N1QL/FTS, some case causes libcouchbase to indicate LCB_SUCCESS, but the meta-data returned is corrupted and not actually parseable as JSON. Originally it was thought that this could be a bug in the Node.js SDK, but the fact that libcouchbase has to parse the response to find the meta, but then returns LCB_SUCCESS with corrupt JSON indicates this is likely not the case.
