 (Compiled from sources)
Qt Version: 5.11.2
Frameworks Version: 5.51.0
Operating System: Linux 4.19.0-gentoo x86_64

-- Information about the crash:
- What I was doing when the application crashed:

Started dragging a folder (didn't drop) on the desktop which shows the desktop folder on top of the background picture.

- Custom settings of the application:

It seems like the desktop is configured as a folder view to show the Desktop folder of the user.

The crash can be reproduced sometimes.

-- Backtrace:
