Hi,
  The following patch makes KListView honor QListViewItem::setRenameEnabled(). 
If there are no objections to this patch, I'll apply it on saturday:

Apart from this, there are several issues with KListView that relate to it 
bypassing the QListView(Item) methods. I guess such code is an artifact of 
the time when Qt did not provide the desired functionality. Much of it is 
implemented using event filters (in one disguise or another) and makes for 
scary reading - any volunteers to help me clean it up post 3.2?
