!!!! Remember, setting the background to white might be what you want, 
but if your REALLY looking for transparancy (i.e. the original 
background colours - which may change with different themes) set the 
colour to NULL.

eg:

   gtk_tree_store_set ( playlist_store, &iter,
        FILE_TREE_COLOR_COLUMN, NULL,
        -1);
