The current version 1.5.1 of the SCP plugin is broken for "password only"
authentication. The current implementation seems to always require a key file.

Assumption:
Check for keyfile entry fails or fallback if first try with key file does not
succeed is not implemented.

(switching back to 1.4 solved the issue for the moment)
