Removing selected items from a list

[Christopher Backhouse <cjbackhouse gmail com>]

I want to remove all the items in a list that the user has highlighted
After discovering that I'm not allowed to use 
gtk_tree_selection_selected_foreach I am trying it like this

GList* 
seln=gtk_tree_selection_get_selected_rows(gtk_tree_view_get_selection(view),&model);
do
{
        GtkTreeIter iter;
        gtk_tree_model_get_iter(model,&iter,(GtkTreePath*)seln->data);
        gtk_list_store_remove(store,&iter);
}
while(seln=seln->next);

The effect of this seems to be to remove only alternate items in 
continuous selections and do something complicated when the selection is 
not continuous.

It looks like the GtkTreePaths that gtk_tree_selection_get_selected_rows 
returns aren't happy about the TreeStore being edited under them. What 
is the correct way to do this?

Probably relevant to this: why are there paths,iters and references? 
wouldn't one have done? I guess there are important differences in their 
behaviour and intended usage that the docs don't make clear.
