Steps:
1. call "auto list = QStandardPaths::standardLocations(QStandardPaths::AppDataLocation);" on OS X

Expected:
list contains:
"~/Library/Application Support/<APPNAME>", "/Library/Application Support/<APPNAME>". "<APPDIR>/../Resources"
(see documentation: http://doc.qt.io/qt-5/qstandardpaths.html#StandardLocation-enum)

Instead:
list contains: "/Library/Application Support/myorg/myapp",
"/Library/Application Support/myorg/myapp", "/Users/myuser/Workspace/build-myapp-Desktop_Qt_5_4_0_clang_64bit-Debug/myapp.app/"

So the first two entries are the same. (I checked that with a string compare.)
Somehow the prefix for using the home directory got lost.
