From Checkmk version 2.1 the Check_MK service crashed if the settings in Hostname translation for piggybacked hosts resulted in an empty host name.
The host name '' is now replaced by '_'. This is consistent with other invalid host names (such as '../../bin/pwn'), where the invalid characters are replaced by an underscore.
