Application: plasmashell (5.16.3)

Qt Version: 5.13.0
Frameworks Version: 5.60.0
Operating System: Linux 5.2.4-1-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- What I was doing when the application crashed:
PlasmaShell frequently crashes upon login to Plasma
- Unusual behavior I noticed:

PlasmaShell frequently crashes upon login to Plasma. 

I manually start it using krunner which I have mapped to a keyboard shortcut. After 2-6 attempts, plasmashell will succeed and the full plasma sessions finished loading the desktop, panels and widgets successfully.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
