It's core dumping because GtkTree->root_tree is not being set (ie, it is NULL).
The GtkTree sources don't first check if this value is non-NULL before
dereferencing it.

Add a call to gtk_widget_map( tree ) before you select it, and all is well.

BTW, someone should submit a fix for this. There needs to be a

g_return_if_fail( tree->root_tree != NULL );

in gtk_real_tree_select_child().
