Description:
Whenever a new connection is created and either a Test Connection or Connect to that new connection happen (specially in SSH over TCP/IP) mode, workbench hangs and need to forcefully close and reopen before it works.

How to repeat:
Simply create a SSH over TCP connection and when it prompt for SSH key acceptance do so, it will hang. 

Suggested fix:
I notice this bug is not actually Workbench but of OpenSSL maybe, as the other day I was working on putty and it happens with it too. It seems when a server RSA key is accepted somehow it doesn't allow process ahead to work. Maybe it is something else but I mostly use SSH over TCP/IP to connect to MySQL server and it always happen when a new connection is created. I encounter this problem on Windows 7, 8, 8.1, 10 on different machine.

Looks like duplicate of http://bugs.mysql.com/bug.php?id=82231?.Thanks.

Nope, the other ticket says it crash when he runs query. But my problem is during making "first attempt" to make connection when it ask to save SSH RSA Key for host. I never has problem running any query or it doesn't hang for connection from second attempt onwards.
