ClangFormat: Code is not indented anymore when creating a project from wizard

Create a Qt Console Application from the wizard. If ClangFormat is loaded, there is no indentation:

#include <QCoreApplication>

int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);

return a.exec();
}

Deactivate the plugin and create another Qt Console Application - the indentation is fine.
