find_members, get_cached_member -> unexpected keyword argument 'location'

dear all

i'm porting an application from silva-1.5.x to silva-2.1.x and i have  
a problem i don't know how to deal with yet.

i get error messages like "get_cached_member() got an unexpected  
keyword argument 'location'" or "find_member() got an unexpected  
keyword argument 'location'", e.g. from this code:

   from AccessControl import getSecurityManager
   user = getSecurityManager().getUser().getId()
   return context.sec_get_member(user).fullname()

i also get the "get_cached_member() got an unexpected keyword argument  
'location'" error in the properties and the access tab of the smi.  
this is strange because my code should only have a negative effect, if  
at all, on the preview tab and not on the others.

to investigate further i have created a completely new silva root in  
the same zope instance with absolutely none of my code. and i get  
again the same error "get_cached_member() got an unexpected keyword  
argument 'location'" in the access tab.

this is zope-2.10, silva-2.1.4, python-2.4.5

and the strange thing: i have a second zope instance with the exact  
same program versions but without this problem...
any advice?

regards,
marc
