Description:
When configured to connect to a MySQL database using SSH tunneling, mysql workbench is crashing. The only way to connect is to make the tunnel using SSH command line and then use it to tunnel the connection, making workbench believe it's doing a simple direct TCP/IP connection to the database. 

How to repeat:
Configure the connection to use SSH Tunnel, put both the passwords in the key chain and try to connect or test connection.

You've tried with Ubuntu, I was using elementary os juno, that is based on Ubuntu 18.04. Maybe this is why you couldn't repeat it. The workbench version you used is the latest 8.0.12?

I checked WorkBench 8.0.12 on Ubuntu 18.04 LTS, please check:

I am having the same exact issue on Ubuntu 18.04 LTS (bionic).

Backtrace:
/lib/x86_64-linux-gnu/libc.so.6(fgets+0x1b)[0x7faad402db3b]
/usr/lib/mysql-workbench/libssh.so.4(+0x1a172)[0x7faad2e3e172]
/usr/lib/mysql-workbench/libssh.so.4(ssh_options_parse_config+0xf2)[0x7faad2e4f30e]
...

I have workbench 8.0.13.

Seems like an invalid option is being passed to the ssh library?

I'm not sure this issue has been addressed but I have been using 8.0 and older on through 8.0.15 on the same Elementary OS Juno without issue for years.  Suddenly it began crashing on ANY attempt to connect via ssh. Having exhausted all attempts to overcome it I then upgraded to 8.0.18 and it worked.... for about an hour.... now it continues to crash again with every attempt to connect.  I have completely uninstalled and reinstalled versions back to 8.0.15 but still get the same result.

I can concur that it only is an issue with ssh connections. I created new connections directly (through vpn) and they are working.
