Yes, that works but now there's another problem, see below. One of the
problems was, I think, that findByPath() never returns None, even if you
ask for a file that doesn't exist. It seems instead you get some undefined
result. But this is a problem with the KDE API, which never returns 0
(that's what the KDE documentation says).
Anyway, I think I've now built a small test case which crashes. I've
attached it, see the comment marked with "***". Make sure that the
filename in self.url really exists. I get "KCrash: crashing...." but the
crash dialog doesn't appear so I don't have a backtrace. Actually it
doesn't always crash, but at least the problem that the returned
name().latin1() contains random characters appears each time.
