This isn't quite right -- get_selected() returns a tuple, never None.
If there's no selection only the treeiter is None. The model will
always be returned.
Try this instead:
selection = treeview.get_selection()
model, treeiter = selection.get_selected()
# If there's no selection, treeiter will be None
if treeiter is not None:
model.remove(treeiter)
As David warns, the 'selection-changed' signal will be emitted
sometimes when there's no current selection. You should always test
before you try to use the selection.
