Not trivial though. The problem is that KDirLister does not store the actual 
items it listed, for that it queries KDirListerCache. So 
KDirLister::addRefreshItem() needs additional information and the only way I 
can think of is to add this by means of another argument. If this method just 
weren't virtual there would be no problem :-(

So my question: Is it BC if I change a virtual function's arguments if this 
virtual function wasn't called by anyone outside kdelibs? (Does anyone know 
if there are apps that derive from KDirLister and reimplement addRefreshItem? 
Not that I could imagine...) If this is not BC, then I can add another, 
non-virtual method and call this instead---which will result in a behavior 
change for deriving KDirListers that reimplement addRefreshItem. And calling 
both methods makes simply absolutely no sense at all.

If nothing of the above is suitable, then I have a problem... didn't come up 
with a better solution yet.
