As commit 3e015d815b3f ("use g_path_get_basename instead of basename")
said, g_path_get_dirname() should be preferred over dirname() since
the former is a portable utility function that has the advantage of not
modifing the string argument.

Replace dirname() with g_path_get_dirname().

          g_path_get_dirname() has the same advantage.
