Empty remote list problem, detailed info

Description

Similar to request 1049781, 843691, 614962.

FileZilla is exhibiting a strange behavior. For just
one server in my list of sites it's displaying an empty
remote directory but not indicating any errors. This
site had no problem when I first started using the app
at 2.2.5 but recently "broke". Upgrading to 2.2.9
didn't resolve it. Switching active/passive has no
effect. There have been no changes to the ftp server
that I'm aware of, and other ftp clients including
various installs of FileZilla still seem to work fine.

Below are transcripts of my sessions with a couple
different configurations. Connecting with normal
customized prefs file:

Times out and disconnects completely. It does register
as the last server connected and makes the reconnect
option available. If I wait a few minutes before trying
to reconnect it behaves this same way. However if I use
reconnect within seconds of the first attempt:

Works perfectly. Remote directory list is filled.

Extra notes:

  • If "show raw directory listing" is enabled, no such

data is shown when connecting with clean prefs the
first time, while the second (successful) try does.
With a customized prefs file this option outputs "Empty
directory listing" as the list data.

  • When displaying an empty list, manually navigating to

a directory that is known to exist is successful, but
subsequently also displays an empty list.

  • Uploading files into an empty listing works. Manually

downloading known existing files works.
