+
+	* app/transform_core.c (transform_core_cut): when transforming
+	a selection in an indexed image, we used to create an indexed
+	tile_buffer. This gives strange (black) results later when we
+	use layer_new_from_tiles() since that function assumes that a
+	TileManager is always RGB or GRAY. Eeek!!
+
+	Instead of fixing it correctly by changing the TileManager 
+	struct, I've unset the keep_indexed flag when calling 
+	gimage_mask_extract(), so whatever layer_new_from_tiles()
+	assumes becomes true. Fixes bug #10762.
