 build available?

 Hi. I've downloaded the snapshot. Cyberduck identifies itself now as:


 {{{
 Version 4.5 (14680)
 }}}

 I've noticed a new screen, after connecting via SFTP:

 [[Image(https://cloud.kluthr.de/public.php?service=files&t=6b20f48a6920887a16eb0bcbbaf23d72&download)]]
 (The message should be clearer :D I think "Immer" should be "Immer
 erlauben" or "Allow always").

 However, the main problem still persists:

 }}}

 BUT: I've found the problem:

 One folder contains a symbolic link, but the target does not exist
 anymore:


 {{{
 lrwxrwxrwx 1 root root        18 May  8 20:59 file -> file.zip
 }}}

 If I try to "download" that link, CD fails. I dont know if this should
 work, but it should be handled :)
