Description Bill Brasky 2016-06-13 21:37:10 UTC 
Application: plasmashell (5.6.90)

Qt Version: 5.6.0
Frameworks Version: 5.24.0
Operating System: Linux 4.4.0-22-generic x86_64
Distribution: KDE neon Developer Edition

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

A compositor icon appears in the system tray, I hover over it and it says "Unknown", I right click and there's only one option to click "Unknown settings", intrigued I click it and plasma crashes and restarts 5 sec later.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
