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:


{{{

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

In 63dbe3d. The 4.5.1 bugfix release is waiting to be approved for release in the Mac App Store. This issue does not affect the non-sandboxed version of Cyberduck available from our website.
