Hi,

If I use the Python FTP instead of Python SFTP, there is no problem. The 
Python library works fine as well as the Filezilla server.
The exception occures inside ssl.py file (line 791) when running 
self.sslobj.shutdown() instruction.

I understand that the problem could be due to Filezilla server as well 
as Python ftplib code and it's difficult to say who is wrong.

I have done 2 snapshots: one on the client side and the second on the 
sever side (see attached document).
On the client side, we can see that the problem occure with the 
/tnr_nemo_dico.pyc/ file.
On the server size, the last line indicates that the transfert is 
succesfull.
It's the reason why I think that the Python FTP lib could have a bug 
when SFTP is in usage. It's a random problem because previous uploads 
have been OK.
Are you agree with me or do I make a mistake ?

Best regards,

Philippe Blanquier
