[Zope] TypeError: unpack non-sequence. RemoteUserFolder?

[leandros van den berg]

Hello,

I made a copy of a live Zope-instance behind a webserver to my PC for 
testing purposes. I just copied the files in 'var' and 'Products' and 
changed the folders in zopectl. I am also running the same Zope version 
(2.8.0) as on the remote server and with the same structure:

Root Folder
|_ ...
|_ acl_users (User Folder)
|_ middelen
    |_ acl_users (Remote User Folder)
    |_ ...
|_ ...

When I try to log in to http://localhost:8080/middelen I get a 
'TypeError: unpack non-sequence' instead of a login-prompt. Logging in 
to http://localhost:8080/manage does work.

Below is the entry from the middelen/error_log:

Does anyone know what the problem might be?
