QtCreator 2.0 crashes application working in QtCreator 1.3

[been_1990]

As the title says... When debugging I receive this error:

Then it shows me where->
qgraphicsitem.cpp:

void QGraphicsItem::setTransform(const QTransform &matrix, bool combine)
{
    if (!d_ptr->transformData)
        d_ptr->transformData = new QGraphicsItemPrivate::TransformData;
 
 //......... etc

void QGraphicsItem::setTransform(const QTransform &matrix, bool combine)
{
    if (!d_ptr->transformData)
        d_ptr->transformData = new QGraphicsItemPrivate::TransformData;

 //......... etc

Apparently anything that uses a image gives me this error. But only using QtCreator 2.0.
