QML memory leaks while using Text elements

[Denis Kochetov]

All greetings. I have problem with memory leaks in QML on win xp sp2. I use my .qml file in C++ code through QDeclarativeView object.

My .qml file:
@
import Qt 4.8

Image
{
id: background
source: "login-background.png"
anchors.verticalCenter: parent.verticalCenter
anchors.horizontalCenter: parent.horizontalCenter

width: 720
height: 576

Text
{
id: textLabel
text: "Hello from login form"
font.bold: true
color: "red"
font.pointSize: 20
font.family: "Helvetica"
anchors.left: parent.left
anchors.top: parent.top
}
}
@
My C++ function that loads and shows this .qml file:
@
int main(int argc, char* argv[])
{

_CrtSetDbgFlag ( _CRTDBG_ALLOC_MEM_DF | _CRTDBG_LEAK_CHECK_DF );

QApplication app( argc, argv );

QWidget mainFrame;

mainFrame.setFixedSize(720, 576);
mainFrame.show();

QDeclarativeView *view = new QDeclarativeView(&mainFrame;);

view->setCacheMode(QGraphicsView::CacheNone);
view->setSource( QUrl::fromLocalFile("LoginForm.qml"));
view->show();
view->deleteLater();

return app.exec();
}
@
After deleting QDeclarativeView object i wait for some time while garbage collector collects all created elements data. Image element data is collected ok after 15 seconds. But Text element data is not collected by garbage collector and causes memory leaks.

Debug Info:

Detected memory leaks!
