Yes, I think.  require() above changes sys.path so that correct GTK+
version (2.0 in your case) is loaded.

There is no alternative I think.  But most of the time you don't need
to worry.  If you do, however, better copy it to some meaningfully
named variable like

	path_to_application = sys.path[0]

before doing anything else.
