Application: plasmashell (5.8.2)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.8.6-1-ARCH x86_64
Distribution: "Arch Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I was starting the system with two monitors and a KDE wallet password prompt appeared, so plasma crashed

- Unusual behavior I noticed:
The wallpaper for one of the monitors didn't appear, and shortly after plasma crashed and was restarted

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