Hi there,

- kdesktop = dcopext.DCOPApp ("kwin", dcop)
+ kdesktop = dcopext.DCOPApp ("kdesktop", dcop)

should do what you expect it to do.

I'm not very familiar with Python and its KDE bindings, but I suggest that
"KBackgroundIface" isn't a valid DCOP object name for the kwin application
and calling getMethods() on such a DCOPObj instance simply returns None. Do
we need an exception?

It would be great if someone could correct me. I'm sure it actually isn't
the way DCOP works here.
