           Product: plasmashell
           Version: 5.13.3
          Platform: Compiled Sources
                OS: Linux

          Assignee: k...@davidedmundson.co.uk
          Reporter: bdbonnai...@gmail.com
                CC: plasma-b...@kde.org
  Target Milestone: 1.0

-- Information about the crash:
- What I was doing when the application crashed:
I have a folder on my desktop, I open it and hover on another folder which
opens it. Inside it whether I grab a folder or a file, plasma crashes when
dropping it onto the desktop.

The crash can be reproduced every time.
