Wow, that has been really a bug:
irb(main):016:0* value = [{"KEY"=>"DocumentRoot", "VALUE"=>"/srv/www/htdocs"}, {"KEY"=>"ServerName", "VALUE"=>"sleposbuilder3.suse.cz.conf"}]
=> [{"KEY"=>"DocumentRoot", "VALUE"=>"/srv/www/htdocs"}, {"KEY"=>"ServerName", "VALUE"=>"sleposbuilder3.suse.cz.conf"}]
irb(main):017:0>  value.none? {|item| item["KEY"] == "HostIP"}
