setPageMargins changes the pageRect incorrectly

After setting the pageMargins to the same values, the pageRect is changed. paperRect stays the same, but is lower than pageRect.

QPrintDialog *pDlg = new QPrintDialog( this );
if ( pDlg->exec() == QDialog::Accepted )

{ QPrinter *p = pDlg->printer(); qreal top,left,right,bottom; qDebug()<<p->pageRect()<<p->paperRect(); //QRect(4,5 191x99) QRect(0,0 198x110) p->getPageMargins( &left, &top, &right, &bottom, QPrinter::Point); p->setPageMargins( left, top, right, bottom, QPrinter::Point); qDebug()<<p->pageRect()<<p->paperRect(); //QRect(12,12 703x1005) QRect(0,0 198x110) }

Output:
QRect(4,5 191x99)
QRect(12,12 703x1005)

The same happens with QPrinter::Point.
