problem with KIO::NetAccess and KDirLister/KFileTreeView

I have a problem with KIO::NetAccess methods and KFileTreeView that uses
KDirLister to monitor a directory.

In the renaming slot of the KFileTreeView, I like to rename a file in the
directory by using the KIO::NetAccess functions copy and del in this way:
   bool success = false;
   if( KIO::NetAccess::exists( targetUrl ) )
      kdDebug(28000)<< "Target already exists - can not copy" << endl;
      if( KIO::NetAccess::copy( fromUrl, targetUrl ))
	 kdDebug(28000) << "Copy success, removing " << fromUrl.prettyURL()
                        << endl;
	 KIO::NetAccess::del( fromUrl );
	 toUrl = targetUrl;
	 success  = true;
	 kdDebug(28000) << "Could not copy:" <<
                           KIO::NetAccess::lastErrorString() << endl;

In KDE 3.0.x that works in that way that the new file is reported by
KDirLister and the file appears in the KFileTreeView and the deleted file
is removed from the tree also by a signal of KDirLister.
In KDE 3.1 (head from today) it is not working. The new file does not appear
as long as the del-function is called. It removes the old line and no new file
is reported. If the del-line is removed from the code above, the new file is
reported correctly, but of course the old one remains.

Well, I fear that you all say 'Do not use NetAccess', and I am willing to change
it in the future. But since the files are locally I used NetAccess to enable
in-treeview-renaming again for Kooka.

Is it possible that changes on KDirLister cause this problem?

Thanks for any help,
