Sentry Crash Report:

Description perillamint 2016-10-17 04:10:57 UTC 
Application: plasmashell (5.8.1)

Qt Version: 5.7.0
Frameworks Version: 5.27.0
Operating System: Linux 4.8.2-nerdanel x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
When I search chromium in application launcher, plasma crashes. It seems some data corruption (maybe icon cache?) occured and Plasma does not know how to handle that corrupted data.

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".
