(300/309) 1774 - FTP 1.0.7 ConnectionManager: "Trying to release connection twice!" on SFTP fetch/save

As the title indicates, every time I fetch/save a file or list a directory through SFTP it works fine but I get this:

<tt>ConnectionManager: java.lang.Exception: Thread[AWT-EventQueue-0,6,main]: Trying to release connection twice!
ConnectionManager: at ftp.Connection.unlock(Connection.java:87)
ConnectionManager: at ftp.ConnectionManager.releaseConnection(ConnectionManager.java:537)
ConnectionManager: at ftp.FtpVFS._endVFSSession(FtpVFS.java:191)</tt>

(activity.log attached)

As I said it's working, but it started showing up recently so I'm curious about the cause and I thought you might be too.

The error message "ftp.FtpVFS._endVFSSession(FtpVFS.java:191)" makes me think you are using FTP protocol._ I am (FTP isn't enabled on the server). Also, the log shows the sftp:// URI and the SSH handshake. _Also, what kind of server are you connecting to? Does it happen with all servers or just some?_ I checked and it happened with Solaris 10 (Solaris SSH); AIX, RHEL3 (OpenSSH). Would it help if I try to reproduce it with a new settings directory?
2014-02-07 22:49:39.823000 ezust	re: clean settings - that would be good. Any other ideas you might have to help me reproduce it would also help, since I can't yet. I am testing with MacOS and Kubuntu Linux openssh servers.
