[Zope] Error defining permissions in ZClass in Zop3-2.3

[Klaus Woelfel]

When I want to define a permission a ZClass or a folder in a ZClass with the 
management - Interface in Zope 2.3, I alwasy get the following error message:

Error Type: TypeError
Error Value: too many arguments; expected 2, got 3

When I did exactly the same thing under the same circumstances in Zope-2.2.5, 
it worked fine.

Because of this error, it's now impossible to access a dtml-method in a 
folder in a ZClassby an object of this ZClass.

Has anybody an indea what I'm might doing wrong, or what has changed in 2.3 
that I have to do it differently an how? 
Or ist this simply a bug?

Thanks,
	Klaus
