Leading blank (again)

[abdolo]

This is not the problem tracked and solved (I searched). This is a new one.
Using 3.3.1.
When on the remote side there is a file that has a leading blank in the name AND the first letter is a capital one, transfer fails.
Using ftpd on FreeBSD 7.2 p4 x86 on remote server.
Steps to reproduce:

• go in console on the ftp server and enter the ftp root
• cp any file from the system: cp /var/log/messages .
• from the client all works ok and can transfer messages file
• mv messages \ messages
• from the client it is ok again, with leading space
• mv \ messages \ Messages
• the client fails to transfer the file

Tried with any kind of file/permission combo, blank+capital seems to be the culprit.

The problem is pretty straight: having the space in front of the file, FileZilla issues a request for the wrong file name
RETR Messages
should be RETR \ Messages

[abdolo]

Also worth to note: in the remote files pane, I see clearly the " Messages" files is left aligned with the others, with no space in front.

Please attach complete logs, snippets are of no use. If possible, enable "Show raw directory listings" in the settings dialog of FileZilla.

Here you are. File names are sent ok. Also to note that IE, FireFox, Squid, BSD ftp treat the file name correctly.

Duplicate of #3032.

Using LIST it is impossible to distinguish leading spaces from padding. You have to upgrade to a server supporting MLSD or refrain from using such exotic filenames.
