Hi,

It is created on the heap. I've hacked together a minimalistic program 
to reproduce the issue, and it has the same issue.
To reproduce the issue:

   1. Compile the code attached
   2. Start dragging the DragWidget and hold it for 5 seconds
   3. After those 5 seconds the DragWidget gets deleted, if you drop
      now, the program will crash

I hope this explains what I'm trying to do better.

Kind Regards,
Martin Grossberger
