Sentry Crash Report:

Description Michael Chinn 2017-02-10 16:43:53 UTC 
Application: plasmashell (5.9.1)

Qt Version: 5.8.0
Frameworks Version: 5.30.0
Operating System: Linux 4.9.7-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed: plasmashell crashes and sometimes restart or stays crashed (off?). Plasmashell crashes/stops once every 2 or 3 hours.  Most crashes occur while the workstation is idle.  This behavior started after 5.9.  The latest 5.9.1-1 release did not remedy this.

The crash can be reproduced every time.

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