[Interest] big trouble with QCoreApplication

[Andy]

Freddy:

What you are suggesting about Qt versions sounds likely.

To see what versions are being used, you could try outputting the version
used to compile and the runtime version in main() like this:

   qDebug().noquote() << "Qt compile version:" << QT_VERSION_STR;
   qDebug().noquote() << "Qt runtime version:" << qVersion();
