[PyQt] QTranslator and QFileDialog problems

I have used static linking to qt_de only in my example. In my real
code I am using the systems locale and I have the same problem with
other languages as well. All Qt translations are working fine except
when using any of 'getOpenFileName', 'getSaveFileName' and
'getExistingDirectory' with QFileDialog which are always displayed in
English. With 'DontUseNativeDialog' option enabled they are translated
correctly. I can live with this problem if this is happening only our
my development machines.

There are 10 kinds of people.
