Hi Petra,

Would you try replacing the following method in GrouperHelper.java:

public static Set getGroupsForPrivileges(GrouperSession s, String[] privs,
			int start, int pageSize, StringBuffer resultCount) throws 
MemberNotFoundException{
                
                Set groupSet = new LinkedHashSet();
                
                Set allSet = new LinkedHashSet();
                
                
                Member member = MemberFinder.findBySubject(s,s.getSubject());
                for (int i = 0; i < privs.length; i++) {

        
allSet.addAll(getGroupsOrStemsWhereMemberHasPriv(member,privs[i].toLowerCase()));
                }

                int end = start + pageSize;
                if (end > allSet.size())
                        end = allSet.size();
                if (resultCount != null) {
                        resultCount.setLength(0);
                        resultCount.append("" + allSet.size());
                }
                
                Iterator it = allSet.iterator();
                Group group = null;
                while(it.hasNext()){
                        try {
                                group = (Group) it.next();
                                groupSet.add(group);
                        }catch(ClassCastException e) {}
                }
                return groupSet;
        }


I think the issue is that the code only expects groups to be returned, but 
some Stems are returned also - which isn't that surprising given the 
getGroupsOrStemsWhereMemberHasPriv method, but I must have changed 
something  elsewhere which has led to a change in behaviour. If you can 
confirm this is the problem, I'll investigate further.
