I tried the second approach described in FAQ 13.25 but it won't work
when using a TreeModelSort (unless I'm missing something). I modified it
to the following code and at least it will remove the correct row, but
it can't handle multiple selections. The iterators doesn't seem to be
valid after removing the first one.

  selection = treeview.get_selection()
  sorted_model, selected = selection.get_selected_rows()
  sorted_iters = [sorted_model.get_iter(path) for path in selected]
  model = sorted_model.get_model()
  for sorted_iter in sorted_iters:
     child_iter = sorted_model.convert_iter_to_child_iter(None,
sorted_iter)
     model.remove(child_iter)



Btw, I think FAQ 13.25 contains an error:

    selection = treeview.get_selection()
    model, selected = selection.get_selected_rows()
    iters = [selection.get_iter(path) for path in selected]
             ^^^^^^^^^
    for iter in iters:
         model.remove(iter)

Shouldn't this be 'model' instead of 'selection'?
