If I'm not mistaken. The iter becomes dead when the model is changed by
an append, etc.. I don't have time to check my facts right now. But It
might shed light on it for you.
I know in our treeview use when we rebuild our data model we look for
the row data that was prevoiusly selected, then after the data is
reloaded we then select that row.
