Setting the cursor still fails because path "1:0" is not visible in
the tree view (although the path does exist in the model).  It is not
visible in the tree view because node "1" is collapsed.  If you expand
node "1" first, then the call to gtk_tree_view_set_cursor() will
succeed as well as the call to gtk_tree_view_get_cursor().

The reason why this is failing now is probably because there have been
some changes in this area in trunk recently, making the behavior more
strict.
