   Yes, because ssh will unexpectedly stop working in automated scripts

   known_hosts file.
   

The real question for me is, why is the server only offering one key or why is the client not checking for the DSA key it already knows?

 

Configure your client to prefer the other algorithm and run it against a 
known server with as many -v options as appropriate.
Read the debug output and the message that ssh displays.
