Comment (by dwinyard):

 Further to this - logging in with a command-line client and issuing a
 'put' to the server in question over-writes an existing file. Using
 Cyberduck, concatenates the file. I've spoken now with the server
 provider, and they've checked the logs and said that Cyberduck is opening
 the file for writing without deleting an existing file with the same name
 in the directory first. Whereas, when we use the command-line client, the
 existing file is deleted before opening the new one for writing.

 I have also changed the preferences in Cyberduck to 'Prompt' instead of
 'Overwrite' and in this case CyberDuck does indeed prompt what to do - so
 it is checking for existing files and finding them. But, when I then click
 'Overwrite' - it then still appends data instead of deleting first.

 Finally - I turned on 'Upload with a temporary filename' - and that fixes
 the issue - in that of course CyberDuck now uploads to a temp file name,
 then issues a REMOVE on the existing file, before renaming the temporary
 file. The CyberDuck log shows this. Lines 160-185 below are with
 'Overwrite' selected, and no temporary filename. Then lines 186+ are for
 with 'Use temporary filename' switched on.

 So 'Use temporary filename' at least provides us with a workaround at the
 moment, but I still feel the 'Overwrite' preference (whether prompted or
 set prejudicially) is not working correctly.
