Bug 414883

Application: plasmashell (5.17.4)
 (Compiled from sources)
Qt Version: 5.13.2
Frameworks Version: 5.64.0
Operating System: Linux 5.4.1-arch1-1 x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed: It does not start and the menu bar does not appear

- Unusual behavior I noticed: When you right click on the desktop the configuration options do not appear

- Custom settings of the application: Nothing special

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
