Application: plasmashell (5.10.4)

Qt Version: 5.9.1
Frameworks Version: 5.37.0
Operating System: Linux 4.12.6-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Just woke up my laptop and tried to unmute volume by shortcut (Fn+F10 key).

- Unusual behavior I noticed:
The frame of volume popup showed just for a second without any content, then Plasma crashed.
After it restarted itself I was able to configure volume, popup was working with no problems.

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