Application: plasmashell (5.8.4)

Qt Version: 5.7.0
Frameworks Version: 5.28.0
Operating System: Linux 4.9.0-0-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- What I was doing when the application crashed:
I was typing in the launcher, specifically the word "battery" and while typing it, it crashed. 
It happened again when I typed "ba" once, but it doesn't seemed to happen everytime.
Nither can I verify that it has to do something with this specific word, it's likely that there is no relation between the word and the crash.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
