Fedora just pushed this to stable, but it affects x2goclient negatively.  On
connect I now get:

The host key for this server was not found but an othertype of key exists.
An attacker might change the default server key to confuse your client into
thinking the key does not exist.
For security reasons, it is recommended to stop the connection.
Do you want to terminate the connection?
