when i acces the ftp via nautilus, it works fine

[Alexander Belchenko (bialix)]

based on traceback the problem is in the bzr core.

[Vincent Ladeuil (vila)]

The traceback suggest that the server fails to return *anything* at the connection phase where it should be at least send a welcome message.

[Martin Pool (mbp)]

This might be due to a firewall forcing the connection closed?

[Vincent Ladeuil (vila)]

@Martin: good point.

It may also be that you're using a proxy requiring you to connect by using user@real-server as the user name and the original password.

bzr uses the ftplib python library and AFAIK the above trick is the only proxy support that exists there.
