Phew, I've found the solution thanks to anda_skoa from Austria who replied

He told me that QX11Info::display() looks like it might need a QApplication instance.

I haven't got any clue (yet) how a Qt program works.
I looked at the main.cpp of a QMake Qt4 project in KDevelop and I added this in myshowdesktop.cpp:
#include <QApplication>
 ...
 int main(int argc, char *argv[])
 {
     QApplication app(argc, argv);
     NETRootInfo info(QX11Info::display(), 0);
     info.setShowingDesktop(true);

 And it runs now without segfault and it minimizes all windows !!
