D6088: [Folder View] Use a copy of QMimeData in signal handler

[Kai Uwe Broulik]

Restricted Application added a project: Plasma.
Restricted Application added a subscriber: plasma-devel.

REVISION SUMMARY
  By the time we leave the method, the QMimeData is deleted by the DragArea's drop event being destroyed leading to a crash.
  
  BUG: 380806
  FIXED-IN: 5.10.1

TEST PLAN
  There's no copy operator. Stackoverflow mentions some weirdness on Windows [1] but that shouldn't affect us.
  
  - Can still re-arrange files
  - Dropping an external file prompts to copy/link/move/create matching applet and all of those options work now without a crash
