Description:
When a connection using SSH (with private key file) is opened and not used for a while (few minutes... sometimes 10 or less) if you try to execute an SQL command the connection is not working anymore (error code 2006 Server Gone away)

The server is of course available and other MYSQL Clients are working fine in the same condition and no outage are logged in mysql server.

This happens since upgrading to the latest version.

Need to open another connection to work.

Keep alive setting in preference does not keep it alive even with a very short interval. 

This happens with my local MYSQL server too.

How to repeat:
Open a SSH connection using a private key file, wait some time, try to use the connection.
