Version: 4.0.3.0-1
Severity: normal

Dear Maintainer,

In following the bug report #472:
http://bugs.x2go.org/db/47/472.html

the reported work-around at:
http://permalink.gmane.org/gmane.linux.terminal-server.x2go.user/2368
was employed. 

The following error was reported:

"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? (no)
Host Key Verification Failed."

The warning did not reply which ssh host key was problematic, nor give an indication of the fingerprint for comparison.
The host keys did not in fact change. It is not clear why there would be a host key problem.
