Similar issue as http://trac.cyberduck.ch/ticket/5294 which was unresolved.

I try to connect to a filezilla server and it disconnects when the STAT command is sent.

Here is the log:

I can replicate a similar issue here when connecting to ftp://ftp.filezilla-project.org. The connection is dropped by the server after sending a FEAT command. This is unexpected.

For this case an error is now reported as of c682ed4.

I suppose the error reported originally is just a failure opening a data connection to the server. We now have fallback in ef7a535. Please reopen if this is still an issue with the latest snapshot build to be available later tomorrow.

I don't think that is the issue as the server still responds to TYPE A.

Please test this using the latest snapshot build available.
