Application: plasmashell (5.3.1)

Qt Version: 5.4.2
Operating System: Linux 4.0.4-3-desktop x86_64
Distribution: "openSUSE 20150611 (Tumbleweed) (x86_64)"

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

I was trying to click on the arrow to show the hidden icons in the tray, at that point the panel freezes and bring me an error and the option to restart Plasma.

The crash can be reproduced sometimes.

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