Your patch leaks the memory returned from g_strdup_printf() when
constructing the tree path. BTW: You don't need to create a string for
the path first (see GtkTreePath documentation).

Other than that, the patch looks good. Dunno how useful the "Invert
Selection" feature is; atleast I've never seen a feature request for
this besides the one from botsie. Maybe others can comment on this?
