Yes, that worked -- and if I just blank out the tiles outside the crop area 
with black transparent pixels I have the illusion of a working crop. But I 
want to delete the tiles. I don't quite understand the data structure of the
tile manager, so I'm blundering about...

What I do now is (after copying the tile to the current memento):

KisTile *deltile = tile;
tile = tile->getNext();
previousTile -> setNext(tile);
delete deltile;

Obviously I also need to remove the entry from the hashtable -- but how do I 
do that?
