Sentry Crash Report:

Description wrightandy19 2017-07-26 13:21:28 UTC 
Application: plasmashell (5.10.3)

Qt Version: 5.9.1
Frameworks Version: 5.36.0
Operating System: Linux 4.12.2-1-MANJARO x86_64
Distribution: "Manjaro Linux"

-- Information about the crash:
- What I was doing when the application crashed:

Opened up the global application menu, then tried to query the string (in my case I wrote 'qt'). The query results (files and apps) appeared for a fraction of a second, then Plasma crashed. Probably the cause is quite different as the situation can't be reproduced, plus for some reason pulseaudio is mentioned in the stack trace.

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