Mac Application Menu always english

[sthepcv]

Hey guys
I have to port a Windows program with Qt UI to Mac OSX. The problem is that the application menu is always in english. I tried such things like http://qt-project.org/forums/viewthread/21134 or setting the "Localization native development region" in my Info.plist to German, but nothing works.
The translation of the other labels is implemented with qm files.
In my <BUNDLE>/Contents/Resources/ directory are only 2 files: the empty qt.conf and my icon file.
Putting a German.lproj dorectory with a localisation.plist or locversin.plist doesn't work.

The program supports only english and german. Is there a way to translate the application menu in regard to the system language?

Hi and welcome to devnet,

You should also add which version of OS X, Qt and Xcode you are using

[sthepcv]

Yes you're right, sorry
I use Mac OSX 10.8.5 with XCode 4.6.2
Qt version is 4.8.4

Can you retry with a more recent version or are you locked on 4.8.4 ?

I'm locked on this version. My company plan to update Qt and the whole development environment, but not until 2015.
