Cyberduck prompts an error "File not found, /bucket/sourcefolder. Please contact your web hosting service provider for assistance." when moving a "folder" from within the bucket in-to an encrypted vault within the same bucket.

The object appears to be copied (visible on refresh) but the original is not removed from it's original location.

Moving a folder containing a file (for example a movie) from outside the vault (in the bucket), to inside a vault appears to behave as expected.

Moving a empty folder from within a vault, into the bucket containing the vault produces the same error, but without copying the folder. Moving a folder containing a file (like a movie) from within a vault, into the bucket containing the vault also produces the same error without copying the requested folder or file.

I have only tested this against actions within the same bucket so far.
