QIcon::addFile() with an invalid filename results in QFile::isNull() == false

      During my cleanup of the icon stuff within QCommon/Fusion style I found that QFile::addIcon() with an invalid filename creates a non-null QIcon instance even if the filename is not found.

      QIcon icon;
icon.addFile("non-existing-icon.png");
if (icon.isNull())
  qDebug() << "Null icon!" << icon;
else
  qDebug() << "Valid icon!" << icon;

      I'm not quite sure if this is by accident or a simple oversight. I would expect that this results in a null QIcon.
