Application: plasmashell (5.9.4)

Qt Version: 5.8.0
Frameworks Version: 5.33.0
Operating System: Linux 4.9.24-1-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- What I was doing when the application crashed:
Had just removed an SD card using another application (Cura), and went to check in the "Device Notifier"

- Unusual behavior I noticed:
The icons in Device Notifier are extremely enlarged.

The crash does not seem to be reproducible.

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