Frequent failed transfert of file

Hello,

I have frequent fail during file transfert with SmartFTP, it works perfectly with Filezilla.
I use Windows 7 x64 RC French and Nod32 4.0.424.0 (the reason is perhaps the AV, I don't know, but no problem with Filezilla).

Example :
[10:20:18] Resolving host name "ftp.xxx.fr"

Post the log from FileZilla.

Please also check the debug log from vsftpd since it's the party that believes that there is a problem.

Please also retry it with the latest version of vsftpd. A couple of SSL/TLS related bugs have been fixed according to their changelog.

Ok, I can't try before a new version in my distribution.
Sorry for the long time between my first post and this answer.
