Application: plasmashell (5.10.4)

Qt Version: 5.9.1
Frameworks Version: 5.37.0
Operating System: Linux 4.12.8-2-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
If you right-click the arrow in the system tray area, then select "System Tray Settings", Plasma shell will crash upon exiting the System Tray Settings.  I can confirm this crash in both openSUSE Tumbleweed and Manjaro's testing branch with the latest updates installed.

The crash can be reproduced every time.

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