[Twisted-Python] ftpclient errors

[Richard Townsend]

I have been experimenting with using ftpclient.py to access some FTP servers on the net, but have been getting errors with the list() and nlst() calls.

I am using Twisted 1.2.0 + Python 2.3.3 + SuSE 8.2

Can anyone shed some light on this problem?
