Drag and Drop Crush when second time drag

[anda_skoa]

And probably an invalid QMimeData pointer as well, since QDrag::setMimeData() takes ownership and if the QDrag instance is destroyed, so will be the QMimeData instance.

Yep

I can't find a QDrag:: start() method, so where did this come from, and how did you get the code to compile in the first place?

Deprecated and thus not part of the API documentation.
But still in the header.
