Segmentation fault when running NETRootInfo info(QX11Info::display(), 0)

[vatbier]

I'm trying to make a program that toggles showdesktop.
I made this from the source code of plasma_applet_showdesktop.so:
NETRootInfo info(QX11Info::display(), 0);
info.setShowingDesktop(true);

But the NetRootInfo constructor gives a segmentation fault.
Can anyone tell me why?

I'm using Mandriva 2009, KDE 4.1.2.
