Description milan zimmermann 2015-05-24 02:30:44 UTC 
Application: plasmashell (5.3.0)

Qt Version: 5.4.1
Operating System: Linux 4.0.3-1-desktop x86_64
Distribution: "openSUSE 20150521 (Tumbleweed) (x86_64)"

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

I clicked on the sound mixer in the System Tray, and immediately Plasma reported crash. 

This is sometimes repeatable.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
