That is the reason for the problem. The patch was to align the  
KConfig::groupList() implementation to the implementation used by 
KConfigGroups(). The old implementation did return results missing some 
childs.

The sorted nature of the returned list was undocumented so i didn't take that 
into account and i'm still not sure i should do.

Perhaps ossi and david have more ideas. but i think the easiest would be for 
kolf to sort the list after getting it. All other apps seem to have no problem 
with the changed behaviour so i would like to not introduce the overhead of 
sorting.
