Qt Version: 5.5.0
Operating System: Linux 4.1.12-1-default x86_64
Distribution: "openSUSE Leap 42.1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
starting luckybackup (admin) package via applauncher

System went sluggish, freeze for a second. Then crash and konqui popup. Applauncher covers up to freeze the screen without vanishing.

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

New crash information added by DrKonqi

plasmashell (5.4.3) using Qt 5.5.1

- What I was doing when the application crashed:

Open "start menu" -> type "steam" -> hit enter to open -> crash.
