Description
click on the file proxy icon in the title bar of a window and drag it across some widget that accepts a drop. The application crashes with this stack trace:

The problem is that the d-pointer is null here:
QPixmap QDrag::dragCursor(Qt::DropAction action) const { typedef QMap<Qt::DropAction, QPixmap>::const_iterator Iterator; Q_D(const QDrag);
That's line 331 of qdrag.cpp.
This is very much like the crash reported in QTBUG-45907 .
