Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-20-generic x86_64
Distribution: Ubuntu 15.04

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

Installed some Window Decorations for KDE, specifically from results found while searching for "glow" and "neon" in the "Get New Decorations" menu for Window Decorations. It crashed when I scrolled to see more of the Window Decorations I installed, so I uninstalled a few Window Decorations and now it doesn't crash anymore. It also crashed if I had the system settings window maximized, therefore viewing more of the Window Decorations available.

The crash can be reproduced every time.

-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
