[maemo-developers] Qt application crashes after 2 minutes if started from app grid

[From: Felipe Crochik]

Can it somehow be related to your desktop file? I can't see anything wrong
with this code.

Hi Timur,

unfortunately I currently can't provide the complete sources. I don't
think I have something special in there. My main() looks mostly like
this:

int main(int argc, char *argv[])
{
#if defined(Q_OS_SYMBIAN)
    QApplication::setGraphicsSystem("openvg");
#else
    QApplication::setGraphicsSystem("raster");
#endif
    QApplication app(argc, argv);
  
    // Export types to QML
    qmlRegisterType<GuideListModel>();
    qmlRegisterType<PoiListModel>();
    qmlRegisterType<TourListModel>();

    qRegisterMetaType<QMediaContent>("QMediaContent");

    Configuration config(app.arguments());
    if (config.hasErrors()) {
        config.printErrors();
        return -1;
    }

    // Init QML view
    QmlApplicationViewer viewer;
    QDeclarativeContext *ctx = viewer.rootContext();
    CoreManager coreManager(config, ctx);
    ctx->setContextProperty("coreManager", &coreManager);

    viewer.setOrientation(QmlApplicationViewer::LockPortrait);
    viewer.setSource(QUrl("qrc:qml/MainWindow.qml"));
    viewer.setResizeMode(QDeclarativeView::SizeRootObjectToView);
    viewer.show();

    return app.exec();
}


Cheers,
Conny
