Hello,

I'm experiencing a strange problem. I've enabled FTP access to my Zope 
instance, but when I try and login it throws an exception:

2009-03-23T11:14:42 INFO ZServer Successful login.

2009-03-23T11:15:07 ERROR ZServer uncaptured python exception, closing

I thought it may be a Plone permissions problem as I was using a Plone 
user account, but even as the Zope admin user it throws the above error. 
Passive mode throws the exception. Active mode doesn't throw an error, 
but doesn't show a directory listing either.

Zope version: Zope 2.10.6-final
OS: Debian Sarge
FTP clients used: FileZilla, standard Linux FTP client and Firefox (as a 
last resort).

Gareth Allen
