Application: systemsettings5 (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-16-generic i686
Distribution: Ubuntu 15.04

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

I was in "Window Decoations" browsing through a collection of alternative styles. The System Settings crashed consitently as I tried to scroll from the second window full to the third. This is an Lenovo Flex 14 laptop with a 1920x1080 screen. There is 6GB ram, so I do not think that it was running out of primary memory.

I have just installed Kubuntu 15.04 over Debian 8 (which was rather user hostile!). By all means contact me at jmdh01@btinternet.com.

The crash can be reproduced every time.
