[PATCH 1/6] Fix some small memory leaks related to gtk_tree_model_get_path()

[Lubomir I. Ivanov]

From: "Lubomir I. Ivanov" <neolit123 at gmail.com>

>From the GTK docs on gtk_tree_model_get_path():
"Returns a newly-created GtkTreePath referenced by iter.
This path should be freed with gtk_tree_path_free()."
