Application: systemsettings (4.11.16)

Qt Version: 4.8.6
Operating System: Linux 4.1.15-desktop-2.mga5 x86_64
Distribution: "Mageia 5"

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

went into system tools to see what program might be running that was rapidly filling up my /home disc which appeared to be copying all the photos and videos it could find on my harddrive to /home/tmp/kde-paul. I kept deleting them and eventually changed the permissionsa on /home/tmp/kde-paul so that nothing could write to it.

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