Thats a bug in your application, Qt doesn't support doing much - if
anything at all - with it until a QApp is created.

Indeed. I can confirm the problem, however it only appears with the
complete example. Just using a static QIcon before creating a QApp
doesn't produce it (i.e. just creating a mainwindow and adding a few
menus is not triggering the problem). So I can just guess its got
something to do with the icon + .ui file.

I also noticed that Qt and PyQt bail out if you use actual files in the
filesystem, as opposed to resources.
