Cyberduck is unable to delete, get or rename a file containing CR (carriage return, char 13). However it is able to upload it. I was only able to delete the file using the terminal and auto-completion of the file name (by pressing the tab-key):

ftp> del Icon\!^M
---> DELE Icon
250 Delete operation successful.

This problem is rather important as there are many Mac-Applications that contain a file called Icon^M. If you'd like to verify: just execute locate "*/Icon?" Everyone uploading such an application using Cyberduck might get completely stuck trying to download or delete it.

Regards and thanks for your work with cyberduck

PS. I just found the old ticket #1392 of Michel Morat who had exactly the same problem, but could not figure out what was the cause.
