#155 closed defect (worksforme)

Cyberduck says "IO error: The SSH key supplied is invalid"

For a certain host I will always get an error message "IO Fehler: The SSH key supplied is invalid". This happens even if no public key authentification is set up, with deleted known_hosts and authorized_keys2 (local and remote). This happened so far in all versions of Cyberduck, including 2.5.4. I include the logfile parts:

Starting a ssh connection from the command line works fine, as does connecting with Fugu (sftp). The ssh config files do not seem to play a role here.
