I've been using Cyberduck for years without any issue, but this morning I am unable to upload files to two ftp servers.

I drag the file into the file list (small php file, 85 bytes), the upload fails with "uploaded 0 bytes of 0 bytes". I can't see any errors at all (or even any attempt to upload) in the FTP log.

This is happening on two production servers — one of which is in our own datacentre — so and I'm confidant it isn't a problem with the server (as at least our server hasn't been changed).

Uploading via ftp in Terminal works fine, as does FileZilla.

I'm running Mac OS X 10.6, nothing has changed that I'm aware of since I last used both servers.
