Unable to select private key when opening SFTP URLs

[Docproc]

I am working with an SFTP server. In Cyberduck, I have set the server up as a Bookmark, using my private key. This works fine.

The problem I am encountering is what happens when I click on an ​sftp:// link in my browser (Chrome). The following happens:

1. Cyberduck opens
2. It presents me with a "Login failed" dialog (even though I've previously been able to use a bookmark for this same site)
3. In the "Login failed" dialog, I uncheck Anonymous login, and enter my FTP username
4. I click "Use Public Key Authentication", the file chooser opens
5. I select my public key (which works in the bookmark), click "Choose"
6. The file chooser closes, but there is no indication that the private key has been selected - the window still says "No private key selected"

There is an error displayed in the system log when I close the file chooser, I've attached it as a text file (some file paths redacted). There is now output in the Cyberduck log drawer.

I am on Mac OS X 10.10.4

Let me know if you need anything else!

Glenn.
