QPrinterInfo::supportedResolutions() for PDF printer - abort on free

On Windows, when the default printer is a PDF printer (CutePDF Writer) the following code will abort :

QPrinterInfo prinfo(QPrinterInfo::defaultPrinter());
QList<int> resolutions = prinfo.supportedResolutions();

The abort happens in QListData::dispose() on the line :

free(d);

The stack at the moment of the abort is :
