[Zope] Problem with Wiki and 2.3.x

[Ricardo Banffy]

Hi.

I am experiencing a problem ever since I moved our Wikis from a 2.2.0
instance to a 2.3.0 (now 2.3.1b2 but the problem persists) that maybe
someone has already experienced (and solved).

It's that simple: the Wikis have been moved from the root of a 2.2.0
instance into a folder called "wiki". They still work (more or less - some
links are broken, but nothing wiki is broken) from there. From that folder
they were .zexp'ed to the 2.3.0 instance and, when I try to get a specific
page, I get the following error:

Error Type: TypeError
Error Value: unexpected keyword argument: client

With the following stack dump:

Traceback (innermost last):

Has anyone solved this one?
