Error when duplicating a folder

[cyberduck]

6ec3a22 created the issue

Up to the last update I used to duplicate some more or less generic folders that contains 2 UTF8 text files after renaming the folder in the "duplicate sub-window". It was successeful up to the update.
Now, with version 5.3.3 (installed 2 days ago):
-I get error "200 Type is now 8-bit binary". Error repeated for the 2 files.
-The navigator window is not refreshed: the new folder does not appear. It appears after manual refreshment.
-The duplicated text files have been created, however they are empty.
The error is repeated after quiting and restarting Cyberduck.

NB: version 5.3.3 is not available in the "Version" listbox below!
