[Warning] Slave SQL: Could not execute Query event. Detailed error: ;, Error_code: 0 (1 reply)

On a multi master setup with 5.6.10 (rhel6) the logs fillup with this message (when using log_warnings 2). I haven't reported this as a bug yet since i'm not fully sure this isn't a setup problem...

My thought are this could be a message about a query/row not to replica on a slave due to replication rules? But then the message should be a notice right?
