Application: plasmashell (5.10.5)

Qt Version: 5.9.1
Frameworks Version: 5.38.0
Operating System: Linux 4.9.44-1-lts x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
I unlocked a session that I had stepped away from, which was locked by SDDM. As soon as I did so, plasma crashed and restarted.

- Unusual behavior I noticed:
I use Redshift, which resulted in the screen flickering a lot upon plasma restarting.

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