#8102: Cyberduck throws NullPointerException during SFTP connect with public key
------------------------+---------------------------
    Reporter:  mmoores  |      Owner:
        Type:  defect   |     Status:  new
    Priority:  normal   |  Milestone:
   Component:  core     |    Version:  4.5
    Severity:  normal   |   Keywords:
Architecture:  Intel    |   Platform:  Mac OS X 10.9
------------------------+---------------------------
 With Version 4.5 (14905), I am trying to "Open Connection" with SFTP to a
 server using Public Key Authentication.
 I checked the checkbox "Use Public Key Authentication", and entered my
 Username.
 The "Anonymous Login" and "Add to Keychain" checkboxes are unchecked.
 My private key is specified ("~/.ssh/id_rsa").

 When I try to connect I get a dialog with "Connection Failed", and no
 additional info.
 I turned on the debug mode and then tried the same action while tailing my
 system.log.
 The output shows an NPE:

 Jul 23 10:38:49 localhost Cyberduck[36006]: [reader] ERROR

 If I execute sftp directly on the command line, I can connect.  I am also
 pasting in the debug output:
