Yes, it's helpful, especially the last few lines in the debug output. It's asking for the passphrase protecting the private key ~/.ssh/id_dsa. If it shouldn't do that, there are 2 possible problem sources: you're using a different key pair (the .bofh key maybe), in which case you can specify it with the -i option.

Or you've used special characters when you entered the passphrase, in which case it might get ugly. Check that your terminals language settings are the same as in your GNOME environment, and that the connection program you're using supports that input method (probably UTF-8)
