Please see my bug report in the KDE bug database
and remove or correct your patch to the Qt library
until the problem in KDE has been fixed!

Bug 117993:
"Wrong return value from static methods in
QKDEIntegration"
http://bugs.kde.org/show_bug.cgi?id=117993

Your file qt.patch in package qt-3.3.4-29.src.rpm
contains the problem. You patch a KDE bug into the
Qt library!

The probem is then of course not only in the
source package, but also in the binary package
compiled from the source...

Please remove the patch for QMessageBox until bug
117993 in KDE has been fixed!


Fix: In my program (http://marc.waeckerlin.org/videorekorder), now I have to use the following workaround:

namespace BUGFIXED_QMessageBox {
   int question(QWidget *parent,
                const QString &caption, const QString &text,
                int button0, int button1=0, int button2=0) {
     int res = ::QMessageBox::question(parent, caption, text,
                                       button0, button1, button2);
     return
       button0 && res==button0
       || button1 && res==button1
       || button2 && res==button2 ? res :
       button0 && res==0 ? button0 :
       button1 && res==1 ? button1 :
       button2 && res==2 ? button2 :
       res;
   }
}

then replace QMessageBox::question by BUGFIXED_QMessageBox::question:

   if (BUGFIXED_QMessageBox::question(0, WARNING,
                             tr("Delete selected files?\n"
                                "Files to delete are:\n")
                             +mrw::join(files, "\n"),
                             QMessageBox::Yes,
                             QMessageBox::No) == QMessageBox::Yes) [...]
