Application: plasmashell (5.9.5)

Qt Version: 5.8.0
Frameworks Version: 5.33.0
Operating System: Linux 4.10.13-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing before the crash:
Laptop was being used on battery without any external peripherals.

- What I was doing when the application crashed:
Had just plugged in 2 monitors and then the USB 3 dock with Ethernet.  Laptop was still powered on.  Monitors flashed and activated as usual.  After the monitors were activated, I noticed the KDE crash dialog saying plasma had crashed, which is how this report was generated.

- Notable information:
I have KDE configured to have 2 taskbar panels - one on the bottom of the laptop's internal display, and another one configured vertically on the left edge of the first external monitor.  I have had issues with panel positioning and resizing in the past with multi-monitor configurations, so maybe this is a related problem.

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